Academic literature on the topic 'Expert systems (Computer science) Geographic information systems Digital mapping'

Digital soil mapping (DSM) offers apparent benefits over more labour-intensive and costly traditional soil survey. Large cartographic scale (e.g. 1 : 10 000 scale) soil maps are rare in Australia, especially in agricultural areas where they are needed to support detailed land evaluation and targeted land management decisions. We describe a DSM expert system using environmental correlation that applies a priori knowledge from a key area (128 ha) soil–landscape with a regionally repeating toposequence to predict the distribution of saline–sodic subsoil patterns in the surrounding upland farming region (2275 ha) in South Australia. Our predictive framework comprises interrelated and iterative steps, including: (i) consolidating a priori knowledge of the key area soil–landscape; (ii) refining existing mentally held and graphic soil–landscape models; (iii) selecting suitable environmental covariates compatible with geographic information systems (GIS) by interrogation via 3D visualisation using a GIS; (iv) transforming the existing soil–landscape models to a computer model; (v) applying the computer model to the environmental variables using the expert system; (vi) performing the predictive mapping; and (vii) validation. The environmental covariates selected include: digital terrain attributes of slope gradient, topographic wetness index and plan curvature, and airborne gamma-radiometric K%. We apply selected soil profile physiochemical data from a prior soil survey to validate mapping. Results showed that we correctly predicted the saline–sodic subsoils in 10 of 11 reference profiles in the region.

The Chemical Movement through Layered Soils (CMLS) model was modified and combined with the USDA-SCS State Soil Geographic Data Base (STATSGO) and Montana Agricultural Potentials System (MAPS) digital databases to assess the likelihood of groundwater contamination from selected herbicides in Teton County, MT. The STATSGO and MAPS databases were overlaid to produce polygons with unique soil and climate characteristics and attribute tables containing only those data needed by the CMLS model. The Weather Generator (WGEN) computer simulation model was modified and used to generate daily precipitation and evapotranspiration values. A new algorithm was developed to estimate soil carbon as a function of soil depth. The depth of movement of the applied chemicals at the end of the growing season was estimated with CMLS for each of the soil series in the STATSGO soil mapping units and the results were entered into ARC/INFO to produce the final hazard maps showing best, weighted average, and worst case results for every unique combination (polygon) of soil mapping unit and climate. County weed infestation maps for leafy spurge and spotted knapweed were digitized and overlaid in ARC/INFO with the CMLS model results for picloram to illustrate how the results might be used to evaluate the threat to groundwater posed by current herbicide applications.

Predictive soil mapping (PSM) can be defined as the development of a numerical or statistical model of the relationship among environmental variables and soil properties, which is then applied to a geographic data base to create a predictive map. PSM is made possible by geocomputational technologies developed over the past few decades. For example, advances in geographic information science, digital terrain modeling, remote sensing, fuzzy logic has created a tremendous potential for improvement in the way that soil maps are produced. The State Factor soil-forming model, which was introduced to the western world by one of the early Presidents of the American Association of Geographers (C.F. Marbut), forms the theoretical basis of PSM. PSM research is being driven by a need to understand the role soil plays in the biophysical and biogeochemical functioning of the planet. Much research has been published on the subject in the last 20 years (mostly outside of geographic journals) and methods have varied widely from statistical approaches (including geostatistics) to more complex methods, such as decision tree analysis, and expert systems. A geographic perspective is needed because of the inherently geographic nature of PSM.

In 1985, the UK government set up a Committee of Enquiry into the Handling of Geographic Information by computer. This was chaired by Lord Chorley and reported in early 1987. It concerned itself with all information which is described in relation to space and which could hence be used either singly or in combination. The tasks undertaken by the Committee are described, as are its composition and method of operation, the major ‘discoveries’ it made, and the recommendations put forward to government. A total of sixty-four recommendations were made covering digital (especially Ordnance Survey) topographic mapping, the availability of geographically disaggregated data, the problems and benefits of linking different data sets together, the need to enhance user awareness of geographical information systems and information technology, education and training, research and development, and the appropriate role for government and machinery for coordination. Finally, the government's published response to the Chorley Report is examined, particularly with regard to the proposed Centre for Geographic Information. The subsequent moves towards a consortium to bring this about are described.

Light detection and Ranging (LiDAR) technology is a valuable tool for archaeological prospection in areas covered by dense vegetation. Its capacity to penetrate dense forest environments enables it to detect archaeological remains scattered over orographically complex areas. LiDAR-derived digital terrain models (DTMs) have made an exceptional contribution towards identifying topographic landscapes of archaeological interest. In this study, we focus on an area of intense historic settlement from the Chalcolithic to the Middle Ages, which today is completely covered by Mediterranean forest. Due to the dense canopy, and the fact that it is a protected area on private land, it has never been analyzed. To reveal the settlement, we primarily used a series of LiDAR mapping surveys to gather data and analyzed other open access remote sensing resources from the National Geographic Institute of Spain (IGN). The IGN LiDAR data proved to be of particular interest. These resources enabled us to detect an ancient fortress (El Viandar Castle) and its surrounding settlement. LiDAR, in conjunction with other products, was fundamental in identifying the site. Equally, the mapping surveys enabled us to analyze the limits and scope of the IGN airborne LiDAR and other free access remote sensing products. Our background in this research demonstrates that low-cost products applied to LiDAR research in archaeology have major limitations when it is necessary to have a high level of spatial resolution in order to define the layout and the main components of an archaeological site.

Rapid urbanization rates impact significantly on the nature of Land Cover patterns of the environment, which has been evident in the depletion of vegetal reserves and in general modifying the human climatic systems (Henderson, et al., 2017; Kumar, Masago, Mishra, & Fukushi, 2018; Luo and Lau, 2017). This study explores remote sensing classification technique and other auxiliary data to determine LULCC for a period of 50 years (1967-2016). The LULCC types identified were quantitatively evaluated using the change detection approach from results of maximum likelihood classification algorithm in GIS. Accuracy assessment results were evaluated and found to be between 56 to 98 percent of the LULC classification. The change detection analysis revealed change in the LULC types in Minna from 1976 to 2016. Built-up area increases from 74.82ha in 1976 to 116.58ha in 2016. Farmlands increased from 2.23 ha to 46.45ha and bared surface increases from 120.00ha to 161.31ha between 1976 to 2016 resulting to decline in vegetation, water body, and wetlands. The Decade of rapid urbanization was found to coincide with the period of increased Public Private Partnership Agreement (PPPA). Increase in farmlands was due to the adoption of urban agriculture which has influence on food security and the environmental sustainability. The observed increase in built up areas, farmlands and bare surfaces has substantially led to reduction in vegetation and water bodies. The oscillatory nature of water bodies LULCC which was not particularly consistent with the rates of urbanization also suggests that beyond the urbanization process, other factors may influence the LULCC of water bodies in urban settlements.

Although I'm a rich white guy, I'm also a feminist anti-racism activist who fights for the rights of the poor and oppressed. (Carl Kenner)Systemic bias is a scourge to the pillar of neutrality. (Cerejota)Count me in. Let's leave the bias to the mainstream media. (Orcar967)Because this is so important. (CuttingEdge)These are a handful of comments posted by online editors who have banded together in a virtual coalition to combat Western bias on the world’s largest digital encyclopedia, Wikipedia. This collective action by Wikipedians both acknowledges the inherent inequalities of a user-controlled information project like Wikpedia and highlights the potential for progressive change within that same project. These community members are taking the responsibility of social change into their own hands (or more aptly, their own keyboards).In recent years much research has emerged on Wikipedia from varying fields, ranging from computer science, to business and information systems, to the social sciences. While critical at times of Wikipedia’s growth, governance, and influence, most of this work observes with optimism that barriers to improvement are not firmly structural, but rather they are socially constructed, leaving open the possibility of important and lasting change for the better.WikiProject: Countering Systemic Bias (WP:CSB) considers one such collective effort. Close to 350 editors have signed on to the project, which began in 2004 and itself emerged from a similar project named CROSSBOW, or the “Committee Regarding Overcoming Serious Systemic Bias on Wikipedia.” As a WikiProject, the term used for a loose group of editors who collaborate around a particular topic, these editors work within the Wikipedia site and collectively create a social network that is unified around one central aim—representing the un- and underrepresented—and yet they are bound by no particular unified set of interests. The first stage of a multi-method study, this paper looks at a snapshot of WP:CSB’s activity from both content analysis and social network perspectives to discover “who” geographically this coalition of the unrepresented is inserting into the digital annals of Wikipedia.Wikipedia and WikipediansDeveloped in 2001 by Internet entrepreneur Jimmy Wales and academic Larry Sanger, Wikipedia is an online collaborative encyclopedia hosting articles in nearly 250 languages (Cohen). The English-language Wikipedia contains over 3.2 million articles, each of which is created, edited, and updated solely by users (Wikipedia “Welcome”). At the time of this study, Alexa, a website tracking organisation, ranked Wikipedia as the 6th most accessed site on the Internet. Unlike the five sites ahead of it though—Google, Facebook, Yahoo, YouTube (owned by Google), and live.com (owned by Microsoft)—all of which are multibillion-dollar businesses that deal more with information aggregation than information production, Wikipedia is a non-profit that operates on less than $500,000 a year and staffs only a dozen paid employees (Lih). Wikipedia is financed and supported by the WikiMedia Foundation, a charitable umbrella organisation with an annual budget of $4.6 million, mainly funded by donations (Middleton).Wikipedia editors and contributors have the option of creating a user profile and participating via a username, or they may participate anonymously, with only an IP address representing their actions. Despite the option for total anonymity, many Wikipedians have chosen to visibly engage in this online community (Ayers, Matthews, and Yates; Bruns; Lih), and researchers across disciplines are studying the motivations of these new online collectives (Kane, Majchrzak, Johnson, and Chenisern; Oreg and Nov). The motivations of open source software contributors, such as UNIX programmers and programming groups, have been shown to be complex and tied to both extrinsic and intrinsic rewards, including online reputation, self-satisfaction and enjoyment, and obligation to a greater common good (Hertel, Niedner, and Herrmann; Osterloh and Rota). Investigation into why Wikipedians edit has indicated multiple motivations as well, with community engagement, task enjoyment, and information sharing among the most significant (Schroer and Hertel). Additionally, Wikipedians seem to be taking up the cause of generativity (a concern for the ongoing health and openness of the Internet’s infrastructures) that Jonathan Zittrain notably called for in The Future of the Internet and How to Stop It. Governance and ControlAlthough the technical infrastructure of Wikipedia is built to support and perhaps encourage an equal distribution of power on the site, Wikipedia is not a land of “anything goes.” The popular press has covered recent efforts by the site to reduce vandalism through a layer of editorial review (Cohen), a tightening of control cited as a possible reason for the recent dip in the number of active editors (Edwards). A number of regulations are already in place that prevent the open editing of certain articles and pages, such as the site’s disclaimers and pages that have suffered large amounts of vandalism. Editing wars can also cause temporary restrictions to editing, and Ayers, Matthews, and Yates point out that these wars can happen anywhere, even to Burt Reynold’s page.Academic studies have begun to explore the governance and control that has developed in the Wikipedia community, generally highlighting how order is maintained not through particular actors, but through established procedures and norms. Konieczny tested whether Wikipedia’s evolution can be defined by Michels’ Iron Law of Oligopoly, which predicts that the everyday operations of any organisation cannot be run by a mass of members, and ultimately control falls into the hands of the few. Through exploring a particular WikiProject on information validation, he concludes:There are few indicators of an oligarchy having power on Wikipedia, and few trends of a change in this situation. The high level of empowerment of individual Wikipedia editors with regard to policy making, the ease of communication, and the high dedication to ideals of contributors succeed in making Wikipedia an atypical organization, quite resilient to the Iron Law. (189)Butler, Joyce, and Pike support this assertion, though they emphasise that instead of oligarchy, control becomes encapsulated in a wide variety of structures, policies, and procedures that guide involvement with the site. A virtual “bureaucracy” emerges, but one that should not be viewed with the negative connotation often associated with the term.Other work considers control on Wikipedia through the framework of commons governance, where “peer production depends on individual action that is self-selected and decentralized rather than hierarchically assigned. Individuals make their own choices with regard to resources managed as a commons” (Viegas, Wattenberg and McKeon). The need for quality standards and quality control largely dictate this commons governance, though interviewing Wikipedians with various levels of responsibility revealed that policies and procedures are only as good as those who maintain them. Forte, Larco, and Bruckman argue “the Wikipedia community has remained healthy in large part due to the continued presence of ‘old-timers’ who carry a set of social norms and organizational ideals with them into every WikiProject, committee, and local process in which they take part” (71). Thus governance on Wikipedia is a strong representation of a democratic ideal, where actors and policies are closely tied in their evolution. Transparency, Content, and BiasThe issue of transparency has proved to be a double-edged sword for Wikipedia and Wikipedians. The goal of a collective body of knowledge created by all—the “expert” and the “amateur”—can only be upheld if equal access to page creation and development is allotted to everyone, including those who prefer anonymity. And yet this very option for anonymity, or even worse, false identities, has been a sore subject for some in the Wikipedia community as well as a source of concern for some scholars (Santana and Wood). The case of a 24-year old college dropout who represented himself as a multiple Ph.D.-holding theology scholar and edited over 16,000 articles brought these issues into the public spotlight in 2007 (Doran; Elsworth). Wikipedia itself has set up standards for content that include expectations of a neutral point of view, verifiability of information, and the publishing of no original research, but Santana and Wood argue that self-policing of these policies is not adequate:The principle of managerial discretion requires that every actor act from a sense of duty to exercise moral autonomy and choice in responsible ways. When Wikipedia’s editors and administrators remain anonymous, this criterion is simply not met. It is assumed that everyone is behaving responsibly within the Wikipedia system, but there are no monitoring or control mechanisms to make sure that this is so, and there is ample evidence that it is not so. (141) At the theoretical level, some downplay these concerns of transparency and autonomy as logistical issues in lieu of the potential for information systems to support rational discourse and emancipatory forms of communication (Hansen, Berente, and Lyytinen), but others worry that the questionable “realities” created on Wikipedia will become truths once circulated to all areas of the Web (Langlois and Elmer). With the number of articles on the English-language version of Wikipedia reaching well into the millions, the task of mapping and assessing content has become a tremendous endeavour, one mostly taken on by information systems experts. Kittur, Chi, and Suh have used Wikipedia’s existing hierarchical categorisation structure to map change in the site’s content over the past few years. Their work revealed that in early 2008 “Culture and the arts” was the most dominant category of content on Wikipedia, representing nearly 30% of total content. People (15%) and geographical locations (14%) represent the next largest categories, while the natural and physical sciences showed the greatest increase in volume between 2006 and 2008 (+213%D, with “Culture and the arts” close behind at +210%D). This data may indicate that contributing to Wikipedia, and thus spreading knowledge, is growing amongst the academic community while maintaining its importance to the greater popular culture-minded community. Further work by Kittur and Kraut has explored the collaborative process of content creation, finding that too many editors on a particular page can reduce the quality of content, even when a project is well coordinated.Bias in Wikipedia content is a generally acknowledged and somewhat conflicted subject (Giles; Johnson; McHenry). The Wikipedia community has created numerous articles and pages within the site to define and discuss the problem. Citing a survey conducted by the University of Würzburg, Germany, the “Wikipedia:Systemic bias” page describes the average Wikipedian as:MaleTechnically inclinedFormally educatedAn English speakerWhiteAged 15-49From a majority Christian countryFrom a developed nationFrom the Northern HemisphereLikely a white-collar worker or studentBias in content is thought to be perpetuated by this demographic of contributor, and the “founder effect,” a concept from genetics, linking the original contributors to this same demographic has been used to explain the origins of certain biases. Wikipedia’s “About” page discusses the issue as well, in the context of the open platform’s strengths and weaknesses:in practice editing will be performed by a certain demographic (younger rather than older, male rather than female, rich enough to afford a computer rather than poor, etc.) and may, therefore, show some bias. Some topics may not be covered well, while others may be covered in great depth. No educated arguments against this inherent bias have been advanced.Royal and Kapila’s study of Wikipedia content tested some of these assertions, finding identifiable bias in both their purposive and random sampling. They conclude that bias favoring larger countries is positively correlated with the size of the country’s Internet population, and corporations with larger revenues work in much the same way, garnering more coverage on the site. The researchers remind us that Wikipedia is “more a socially produced document than a value-free information source” (Royal & Kapila).WikiProject: Countering Systemic BiasAs a coalition of current Wikipedia editors, the WikiProject: Countering Systemic Bias (WP:CSB) attempts to counter trends in content production and points of view deemed harmful to the democratic ideals of a valueless, open online encyclopedia. WP:CBS’s mission is not one of policing the site, but rather deepening it:Generally, this project concentrates upon remedying omissions (entire topics, or particular sub-topics in extant articles) rather than on either (1) protesting inappropriate inclusions, or (2) trying to remedy issues of how material is presented. Thus, the first question is "What haven't we covered yet?", rather than "how should we change the existing coverage?" (Wikipedia, “Countering”)The project lays out a number of content areas lacking adequate representation, geographically highlighting the dearth in coverage of Africa, Latin America, Asia, and parts of Eastern Europe. WP:CSB also includes a “members” page that editors can sign to show their support, along with space to voice their opinions on the problem of bias on Wikipedia (the quotations at the beginning of this paper are taken from this “members” page). At the time of this study, 329 editors had self-selected and self-identified as members of WP:CSB, and this group constitutes the population sample for the current study. To explore the extent to which WP:CSB addressed these self-identified areas for improvement, each editor’s last 50 edits were coded for their primary geographical country of interest, as well as the conceptual category of the page itself (“P” for person/people, “L” for location, “I” for idea/concept, “T” for object/thing, or “NA” for indeterminate). For example, edits to the Wikipedia page for a single person like Tony Abbott (Australian federal opposition leader) were coded “Australia, P”, while an edit for a group of people like the Manchester United football team would be coded “England, P”. Coding was based on information obtained from the header paragraphs of each article’s Wikipedia page. After coding was completed, corresponding information on each country’s associated continent was added to the dataset, based on the United Nations Statistics Division listing.A total of 15,616 edits were coded for the study. Nearly 32% (n = 4962) of these edits were on articles for persons or people (see Table 1 for complete coding results). From within this sub-sample of edits, a majority of the people (68.67%) represented are associated with North America and Europe (Figure A). If we break these statistics down further, nearly half of WP:CSB’s edits concerning people were associated with the United States (36.11%) and England (10.16%), with India (3.65%) and Australia (3.35%) following at a distance. These figures make sense for the English-language Wikipedia; over 95% of the population in the three Westernised countries speak English, and while India is still often regarded as a developing nation, its colonial British roots and the emergence of a market economy with large, technology-driven cities are logical explanations for its representation here (and some estimates make India the largest English-speaking nation by population on the globe today).Table A Coding Results Total Edits 15616 (I) Ideas 2881 18.45% (L) Location 2240 14.34% NA 333 2.13% (T) Thing 5200 33.30% (P) People 4962 31.78% People by Continent Africa 315 6.35% Asia 827 16.67% Australia 175 3.53% Europe 1411 28.44% NA 110 2.22% North America 1996 40.23% South America 128 2.58% The areas of the globe of main concern to WP:CSB proved to be much less represented by the coalition itself. Asia, far and away the most populous continent with more than 60% of the globe’s people (GeoHive), was represented in only 16.67% of edits. Africa (6.35%) and South America (2.58%) were equally underrepresented compared to both their real-world populations (15% and 9% of the globe’s population respectively) and the aforementioned dominance of the advanced Westernised areas. However, while these percentages may seem low, in aggregate they do meet the quota set on the WP:CSB Project Page calling for one out of every twenty edits to be “a subject that is systematically biased against the pages of your natural interests.” By this standard, the coalition is indeed making headway in adding content that strategically counterbalances the natural biases of Wikipedia’s average editor.Figure ASocial network analysis allows us to visualise multifaceted data in order to identify relationships between actors and content (Vego-Redondo; Watts). Similar to Davis’s well-known sociological study of Southern American socialites in the 1930s (Scott), our Wikipedia coalition can be conceptualised as individual actors united by common interests, and a network of relations can be constructed with software such as UCINET. A mapping algorithm that considers both the relationship between all sets of actors and each actor to the overall collective structure produces an image of our network. This initial network is bimodal, as both our Wikipedia editors and their edits (again, coded for country of interest) are displayed as nodes (Figure B). Edge-lines between nodes represents a relationship, and here that relationship is the act of editing a Wikipedia article. We see from our network that the “U.S.” and “England” hold central positions in the network, with a mass of editors crowding around them. A perimeter of nations is then held in place by their ties to editors through the U.S. and England, with a second layer of editors and poorly represented nations (Gabon, Laos, Uzbekistan, etc.) around the boundaries of the network.Figure BWe are reminded from this visualisation both of the centrality of the two Western powers even among WP:CSB editoss, and of the peripheral nature of most other nations in the world. But we also learn which editors in the project are contributing most to underrepresented areas, and which are less “tied” to the Western core. Here we see “Wizzy” and “Warofdreams” among the second layer of editors who act as a bridge between the core and the periphery; these are editors with interests in both the Western and marginalised nations. Located along the outer edge, “Gallador” and “Gerrit” have no direct ties to the U.S. or England, concentrating all of their edits on less represented areas of the globe. Identifying editors at these key positions in the network will help with future research, informing interview questions that will investigate their interests further, but more significantly, probing motives for participation and action within the coalition.Additionally, we can break the network down further to discover editors who appear to have similar interests in underrepresented areas. Figure C strips down the network to only editors and edits dealing with Africa and South America, the least represented continents. From this we can easily find three types of editors again: those who have singular interests in particular nations (the outermost layer of editors), those who have interests in a particular region (the second layer moving inward), and those who have interests in both of these underrepresented regions (the center layer in the figure). This last group of editors may prove to be the most crucial to understand, as they are carrying the full load of WP:CSB’s mission.Figure CThe End of Geography, or the Reclamation?In The Internet Galaxy, Manuel Castells writes that “the Internet Age has been hailed as the end of geography,” a bold suggestion, but one that has gained traction over the last 15 years as the excitement for the possibilities offered by information communication technologies has often overshadowed structural barriers to participation like the Digital Divide (207). Castells goes on to amend the “end of geography” thesis by showing how global information flows and regional Internet access rates, while creating a new “map” of the world in many ways, is still closely tied to power structures in the analog world. The Internet Age: “redefines distance but does not cancel geography” (207). The work of WikiProject: Countering Systemic Bias emphasises the importance of place and representation in the information environment that continues to be constructed in the online world. This study looked at only a small portion of this coalition’s efforts (~16,000 edits)—a snapshot of their labor frozen in time—which itself is only a minute portion of the information being dispatched through Wikipedia on a daily basis (~125,000 edits). Further analysis of WP:CSB’s work over time, as well as qualitative research into the identities, interests and motivations of this collective, is needed to understand more fully how information bias is understood and challenged in the Internet galaxy. The data here indicates this is a fight worth fighting for at least a growing few.ReferencesAlexa. “Top Sites.” Alexa.com, n.d. 10 Mar. 2010 ‹http://www.alexa.com/topsites>.

Special Care Notice This article contains images of deceased people that might cause sadness or distress to Aboriginal and Torres Strait Islander readers. Introduction Like many cities, Perth was founded on wetlands that have been integral to its history and culture (Seddon 226–32). However, in order to promote a settlement agenda, early mapmakers sought to erase the city’s wetlands from cartographic depictions (Giblett, Cities). Since the colonial era, inner-Perth’s swamps and lakes have been drained, filled, significantly reduced in size, or otherwise reclaimed for urban expansion (Bekle). Not only have the swamps and lakes physically disappeared, the memories of their presence and influence on the city’s development over time are also largely forgotten. What was the site of Perth, specifically its wetlands, like before British settlement? In 2014, an interdisciplinary team at Edith Cowan University developed a digital visualisation process to re-imagine Perth prior to colonisation. This was based on early maps of the Swan River Colony and a range of archival information. The images depicted the city’s topography, hydrology, and vegetation and became the centerpiece of a physical exhibition entitled Re-imagining Perth’s Lost Wetlands and a virtual exhibition hosted by the Western Australian Museum. Alongside historic maps, paintings, photographs, and writings, the visual reconstruction of Perth aimed to foster appreciation of the pre-settlement environment—the homeland of the Whadjuck Nyoongar, or Bibbulmun, people (Carter and Nutter). The exhibition included the narrative of Fanny Balbuk, a Nyoongar woman who voiced her indignation over the “usurping of her beloved home ground” (Bates, The Passing 69) by flouting property lines and walking through private residences to reach places of cultural significance. Beginning with Balbuk’s story and the digital tracing of her walking route through colonial Perth, this article discusses the project in the context of contemporary pressures on the city’s extant wetlands. The re-imagining of Perth through historically, culturally, and geographically-grounded digital visualisation approaches can inspire the conservation of its wetlands heritage. Balbuk’s Walk through the City For many who grew up in Perth, Fanny Balbuk’s perambulations have achieved legendary status in the collective cultural imagination. In his memoir, David Whish-Wilson mentions Balbuk’s defiant walks and the lighting up of the city for astronaut John Glenn in 1962 as the two stories that had the most impact on his Perth childhood. From Gordon Stephenson House, Whish-Wilson visualises her journey in his mind’s eye, past Government House on St Georges Terrace (the main thoroughfare through the city centre), then north on Barrack Street towards the railway station, the site of Lake Kingsford where Balbuk once gathered bush tucker (4). He considers the footpaths “beneath the geometric frame of the modern city […] worn smooth over millennia that snake up through the sheoak and marri woodland and into the city’s heart” (Whish-Wilson 4). Balbuk’s story embodies the intertwined culture and nature of Perth—a city of wetlands. Born in 1840 on Heirisson Island, Balbuk (also known as Yooreel) (Figure 1) had ancestral bonds to the urban landscape. According to Daisy Bates, writing in the early 1900s, the Nyoongar term Matagarup, or “leg deep,” denotes the passage of shallow water near Heirisson Island where Balbuk would have forded the Swan River (“Oldest” 16). Yoonderup was recorded as the Nyoongar name for Heirisson Island (Bates, “Oldest” 16) and the birthplace of Balbuk’s mother (Bates, “Aboriginal”). In the suburb of Shenton Park near present-day Lake Jualbup, her father bequeathed to her a red ochre (or wilgi) pit that she guarded fervently throughout her life (Bates, “Aboriginal”).Figure 1. Group of Aboriginal Women at Perth, including Fanny Balbuk (far right) (c. 1900). Image Credit: State Library of Western Australia (Image Number: 44c). Balbuk’s grandparents were culturally linked to the site. At his favourite camp beside the freshwater spring near Kings Park on Mounts Bay Road, her grandfather witnessed the arrival of Lieutenant-Colonel Frederick Irwin, cousin of James Stirling (Bates, “Fanny”). In 1879, colonial entrepreneurs established the Swan Brewery at this significant locale (Welborn). Her grandmother’s gravesite later became Government House (Bates, “Fanny”) and she protested vociferously outside “the stone gates guarded by a sentry [that] enclosed her grandmother’s burial ground” (Bates, The Passing 70). Balbuk’s other grandmother was buried beneath Bishop’s Grove, the residence of the city’s first archibishop, now Terrace Hotel (Bates, “Aboriginal”). Historian Bob Reece observes that Balbuk was “the last full-descent woman of Kar’gatta (Karrakatta), the Bibbulmun name for the Mount Eliza [Kings Park] area of Perth” (134). According to accounts drawn from Bates, her home ground traversed the area between Heirisson Island and Perth’s north-western limits. In Kings Park, one of her relatives was buried near a large, hollow tree used by Nyoongar people like a cistern to capture water and which later became the site of the Queen Victoria Statue (Bates, “Aboriginal”). On the slopes of Mount Eliza, the highest point of Kings Park, at the western end of St Georges Terrace, she harvested plant foods, including zamia fruits (Macrozamia riedlei) (Bates, “Fanny”). Fanny Balbuk’s knowledge contributed to the native title claim lodged by Nyoongar people in 2006 as Bennell v. State of Western Australia—the first of its kind to acknowledge Aboriginal land rights in a capital city and part of the larger Single Nyoongar Claim (South West Aboriginal Land and Sea Council et al.). Perth’s colonial administration perceived the city’s wetlands as impediments to progress and as insalubrious environments to be eradicated through reclamation practices. For Balbuk and other Nyoongar people, however, wetlands were “nourishing terrains” (Rose) that afforded sustenance seasonally and meaning perpetually (O’Connor, Quartermaine, and Bodney). Mary Graham, a Kombu-merri elder from Queensland, articulates the connection between land and culture, “because land is sacred and must be looked after, the relation between people and land becomes the template for society and social relations. Therefore all meaning comes from land.” Traditional, embodied reliance on Perth’s wetlands is evident in Bates’ documentation. For instance, Boojoormeup was a “big swamp full of all kinds of food, now turned into Palmerston and Lake streets” (Bates, “Aboriginal”). Considering her cultural values, Balbuk’s determination to maintain pathways through the increasingly colonial Perth environment is unsurprising (Figure 2). From Heirisson Island: a straight track had led to the place where once she had gathered jilgies [crayfish] and vegetable food with the women, in the swamp where Perth railway station now stands. Through fences and over them, Balbuk took the straight track to the end. When a house was built in the way, she broke its fence-palings with her digging stick and charged up the steps and through the rooms. (Bates, The Passing 70) One obstacle was Hooper’s Fence, which Balbuk broke repeatedly on her trips to areas between Kings Park and the railway station (Bates, “Hooper’s”). Her tenacious commitment to walking ancestral routes signifies the friction between settlement infrastructure and traditional Nyoongar livelihood during an era of rapid change. Figure 2.

Project Background and Approach Inspired by Fanny Balbuk’s story, Re-imagining Perth’s Lost Wetlands began as an Australian response to the Mannahatta Project. Founded in 1999, that project used spatial analysis techniques and mapping software to visualise New York’s urbanised Manhattan Island—or Mannahatta as it was called by indigenous people—in the early 1600s (Sanderson). Based on research into the island’s original biogeography and the ecological practices of Native Americans, Mannahatta enabled the public to “peel back” the city’s strata, revealing the original composition of the New York site. The layers of visuals included rich details about the island’s landforms, water systems, and vegetation. Mannahatta compelled Rod Giblett, a cultural researcher at Edith Cowan University, to develop an analogous model for visualising Perth circa 1829. The idea attracted support from the City of Perth, Landgate, and the University. Using stories, artefacts, and maps, the team—comprising a cartographer, designer, three-dimensional modelling expert, and historical researchers—set out to generate visualisations of the landscape at the time of British colonisation. Nyoongar elder Noel Nannup approved culturally sensitive material and contributed his perspective on Aboriginal content to include in the exhibition. The initiative’s context remains pressing. In many ways, Perth has become a template for development in the metropolitan area (Weller). While not unusual for a capital, the rate of transformation is perhaps unexpected in a city less than 200 years old (Forster). There also remains a persistent view of existing wetlands as obstructions to progress that, once removed, are soon forgotten (Urban Bushland Council). Digital visualisation can contribute to appreciating environments prior to colonisation but also to re-imagining possibilities for future human interactions with land, water, and space. Despite the rapid pace of change, many Perth area residents have memories of wetlands lost during their lifetimes (for example, Giblett, Forrestdale). However, as the clearing and drainage of the inner city occurred early in settlement, recollections of urban wetlands exist exclusively in historical records. In 1935, a local correspondent using the name “Sandgroper” reminisced about swamps, connecting them to Perth’s colonial heritage: But the Swamps were very real in fact, and in name in the [eighteen-] Nineties, and the Perth of my youth cannot be visualised without them. They were, of course, drying up apace, but they were swamps for all that, and they linked us directly with the earliest days of the Colony when our great-grandparents had founded this City of Perth on a sort of hog's-back, of which Hay-street was the ridge, and from which a succession of streamlets ran down its southern slope to the river, while land locked to the north of it lay a series of lakes which have long since been filled to and built over so that the only evidence that they have ever existed lies in the original street plans of Perth prepared by Roe and Hillman in the early eighteen-thirties. A salient consequence of the loss of ecological memory is the tendency to repeat the miscues of the past, especially the blatant disregard for natural and cultural heritage, as suburbanisation engulfs the area. While the swamps of inner Perth remain only in the names of streets, existing wetlands in the metropolitan area are still being threatened, as the Roe Highway (Roe 8) Campaign demonstrates. To re-imagine Perth’s lost landscape, we used several colonial survey maps to plot the location of the original lakes and swamps. At this time, a series of interconnecting waterbodies, known as the Perth Great Lakes, spread across the north of the city (Bekle and Gentilli). This phase required the earliest cartographic sources (Figure 3) because, by 1855, city maps no longer depicted wetlands. We synthesised contextual information, such as well depths, geological and botanical maps, settlers’ accounts, Nyoongar oral histories, and colonial-era artists’ impressions, to produce renderings of Perth. This diverse collection of primary and secondary materials served as the basis for creating new images of the city. Team member Jeff Murray interpolated Balbuk’s route using historical mappings and accounts, topographical data, court records, and cartographic common sense. He determined that Balbuk would have camped on the high ground of the southern part of Lake Kingsford rather than the more inundated northern part (Figure 2). Furthermore, she would have followed a reasonably direct course north of St Georges Terrace (contrary to David Whish-Wilson’s imaginings) because she was barred from Government House for protesting. This easier route would have also avoided the springs and gullies that appear on early maps of Perth. Figure 3. Townsite of Perth in Western Australia by Colonial Draftsman A. Hillman and John Septimus Roe (1838). This map of Perth depicts the wetlands that existed overlaid by the geomentric grid of the new city. Image Credit: State Library of Western Australia (Image Number: BA1961/14). Additionally, we produced an animated display based on aerial photographs to show the historical extent of change. Prompted by the build up to World War II, the earliest aerial photography of Perth dates from the late 1930s (Dixon 148–54). As “Sandgroper” noted, by this time, most of the urban wetlands had been drained or substantially modified. The animation revealed considerable alterations to the formerly swampy Swan River shoreline. Most prominent was the transformation of the Matagarup shallows across the Swan River, originally consisting of small islands. Now traversed by a causeway, this area was transformed into a single island, Heirisson—the general site of Balbuk’s birth. The animation and accompanying materials (maps, images, and writings) enabled viewers to apprehend the changes in real time and to imagine what the city was once like. Re-imagining Perth’s Urban Heart The physical environment of inner Perth includes virtually no trace of its wetland origins. Consequently, we considered whether a representation of Perth, as it existed previously, could enhance public understanding of natural heritage and thereby increase its value. For this reason, interpretive materials were exhibited centrally at Perth Town Hall. Built partly by convicts between 1867 and 1870, the venue is close to the site of the 1829 Foundation of Perth, depicted in George Pitt Morrison’s painting. Balbuk’s grandfather “camped somewhere in the city of Perth, not far from the Town Hall” (Bates, “Fanny”). The building lies one block from the site of the railway station on the site of Lake Kingsford, the subsistence grounds of Balbuk and her forebears: The old swamp which is now the Perth railway yards had been a favourite jilgi ground; a spring near the Town Hall had been a camping place of Maiago […] and others of her fathers' folk; and all around and about city and suburbs she had gathered roots and fished for crayfish in the days gone by. (Bates, “Derelicts” 55) Beginning in 1848, the draining of Lake Kingsford reached completion during the construction of the Town Hall. While the swamps of the city were not appreciated by many residents, some organisations, such as the Perth Town Trust, vigorously opposed the reclamation of the lake, alluding to its hydrological role: That, the soil being sand, it is not to be supposed that Lake Kingsford has in itself any material effect on the wells of Perth; but that, from this same reason of the sandy soil, it would be impossible to keep the lake dry without, by so doing, withdrawing the water from at least the adjacent parts of the townsite to the same depth. (Independent Journal of Politics and News 3) At the time of our exhibition, the Lake Kingsford site was again being reworked to sink the railway line and build Yagan Square, a public space named after a colonial-era Nyoongar leader. The project required specialised construction techniques due to the high water table—the remnants of the lake. People travelling to the exhibition by train in October 2014 could have seen the lake reasserting itself in partly-filled depressions, flush with winter rain (Figure 4).Figure 4. Rise of the Repressed (2014). Water Rising in the former site of Lake Kingsford/Irwin during construction, corner of Roe and Fitzgerald Streets, Northbridge, WA. Image Credit: Nandi Chinna (2014). The exhibition was situated in the Town Hall’s enclosed undercroft designed for markets and more recently for shops. While some visited after peering curiously through the glass walls of the undercroft, others hailed from local and state government organisations. Guest comments applauded the alternative view of Perth we presented. The content invited the public to re-imagine Perth as a city of wetlands that were both environmentally and culturally important. A display panel described how the city’s infrastructure presented a hindrance for Balbuk as she attempted to negotiate the once-familiar route between Yoonderup and Lake Kingsford (Figure 2). Perth’s growth “restricted Balbuk’s wanderings; towns, trains, and farms came through her ‘line of march’; old landmarks were thus swept away, and year after year saw her less confident of the locality of one-time familiar spots” (Bates, “Fanny”). Conserving Wetlands: From Re-Claiming to Re-Valuing? Imagination, for philosopher Roger Scruton, involves “thinking of, and attending to, a present object (by thinking of it, or perceiving it, in terms of something absent)” (155). According to Scruton, the feelings aroused through imagination can prompt creative, transformative experiences. While environmental conservation tends to rely on data-driven empirical approaches, it appeals to imagination less commonly. We have found, however, that attending to the present object (the city) in terms of something absent (its wetlands) through evocative visual material can complement traditional conservation agendas focused on habitats and species. The actual extent of wetlands loss in the Swan Coastal Plain—the flat and sandy region extending from Jurien Bay south to Cape Naturaliste, including Perth—is contested. However, estimates suggest that 80 per cent of wetlands have been lost, with remaining habitats threatened by climate change, suburban development, agriculture, and industry (Department of Environment and Conservation). As with the swamps and lakes of the inner city, many regional wetlands were cleared, drained, or filled before they could be properly documented. Additionally, the seasonal fluctuations of swampy places have never been easily translatable to two-dimensional records. As Giblett notes, the creation of cartographic representations and the assignment of English names were attempts to fix the dynamic boundaries of wetlands, at least in the minds of settlers and administrators (Postmodern 72–73). Moreover, European colonists found the Western Australian landscape, including its wetlands, generally discomfiting. In a letter from 1833, metaphors failed George Fletcher Moore, the effusive colonial commentator, “I cannot compare these swamps to any marshes with which you are familiar” (220). The intermediate nature of wetlands—as neither land nor lake—is perhaps one reason for their cultural marginalisation (Giblett, Postmodern 39). The conviction that unsanitary, miasmic wetlands should be converted to more useful purposes largely prevailed (Giblett, Black 105–22). Felicity Morel-EdnieBrown’s research into land ownership records in colonial Perth demonstrated that town lots on swampland were often preferred. By layering records using geographic information systems (GIS), she revealed modifications to town plans to accommodate swampland frontages. The decline of wetlands in the region appears to have been driven initially by their exploitation for water and later for fertile soil. Northern market gardens supplied the needs of the early city. It is likely that the depletion of Nyoongar bush foods predated the flourishing of these gardens (Carter and Nutter). Engaging with the history of Perth’s swamps raises questions about the appreciation of wetlands today. In an era where numerous conservation strategies and alternatives have been developed (for example, Bobbink et al. 93–220), the exploitation of wetlands in service to population growth persists. On Perth’s north side, wetlands have long been subdued by controlling their water levels and landscaping their boundaries, as the suburban examples of Lake Monger and Hyde Park (formerly Third Swamp Reserve) reveal. Largely unmodified wetlands, such as Forrestdale Lake, exist south of Perth, but they too are in danger (Giblett, Black Swan). The Beeliar Wetlands near the suburb of Bibra Lake comprise an interconnected series of lakes and swamps that are vulnerable to a highway extension project first proposed in the 1950s. Just as the Perth Town Trust debated Lake Kingsford’s draining, local councils and the public are fiercely contesting the construction of the Roe Highway, which will bisect Beeliar Wetlands, destroying Roe Swamp (Chinna). The conservation value of wetlands still struggles to compete with traffic planning underpinned by a modernist ideology that associates cars and freeways with progress (Gregory). Outside of archives, the debate about Lake Kingsford is almost entirely forgotten and its physical presence has been erased. Despite the magnitude of loss, re-imagining the city’s swamplands, in the way that we have, calls attention to past indiscretions while invigorating future possibilities. We hope that the re-imagining of Perth’s wetlands stimulates public respect for ancestral tracks and songlines like Balbuk’s. Despite the accretions of settler history and colonial discourse, songlines endure as a fundamental cultural heritage. Nyoongar elder Noel Nannup states, “as people, if we can get out there on our songlines, even though there may be farms or roads overlaying them, fences, whatever it is that might impede us from travelling directly upon them, if we can get close proximity, we can still keep our culture alive. That is why it is so important for us to have our songlines.” Just as Fanny Balbuk plied her songlines between Yoonderup and Lake Kingsford, the traditional custodians of Beeliar and other wetlands around Perth walk the landscape as an act of resistance and solidarity, keeping the stories of place alive.

IntroductionOver three days in November 2017, 400 people gathered for a conference at the Sam’s Town Hotel and Gambling Hall in Las Vegas, Nevada. The majority of attendees were fiction authors but the conference program looked like no ordinary writer’s festival; there were no in-conversation interviews with celebrity authors, no panels on the politics of the book industry and no books launched or promoted. Instead, this was a gathering called 20Books2017, a self-publishing conference about the business of fiction ebooks and there was expertise in the room.Among those attending, 50 reportedly earned over $100,000 US per annum, with four said to be earning in excess of $1,000,000 US year. Yet none of these authors are household names. Their work is not adapted to film or television. Their books cannot be found on the shelves of brick-and-mortar bookstores. For the most part, these authors go unrepresented by the publishing industry and literary agencies, and further to which, only a fraction have ever actively pursued traditional publishing. Instead, they write for and sell into a commercial fiction market dominated by a single retailer and publisher: online retailer Amazon.While the online ebook market can be dynamic and lucrative, it can also be chaotic. Unlike the traditional publishing industry—an industry almost stoically adherent to various gatekeeping processes: an influential agent-class, formalized education pathways, geographic demarcations of curatorial power (see Thompson)—the nascent ebook market is unmapped and still somewhat ungoverned. As will be discussed below, even the markets directly engineered by Amazon are subject to rapid change and upheaval. It can be a space with shifting boundaries and thus, for many in the traditional industry both Amazon and self-publishing come to represent a type of encroaching northern dread.In the eyes of the traditional industry, digital self-publishing certainly conforms to the barbarous north of European literary metaphor: Orwell’s ‘real ugliness of industrialism’ (94) governed by the abject lawlessness of David Peace’s Yorkshire noir (Fowler). But for adherents within the day-to-day of self-publishing, this unruly space also provides the frontiers and gold-rushes of American West mythology.What remains uncertain is the future of both the traditional and the self-publishing sectors and the degree to which they will eventually merge, overlap and/or co-exist. So-called ‘hybrid-authors’ (those self-publishing and involved in traditional publication) are becoming increasingly common—especially in genre fiction—but the disruption brought about by self-publishing and ebooks appears far from complete.To the contrary, the Amazon-led ebook iteration of this market is relatively new. While self-publishing and independent publishing have long histories as modes of production, Amazon launched both its Kindle e-reader device and its marketplace Kindle Direct Publishing (KDP) a little over a decade ago. In the years subsequent, the integration of KDP within the Amazon retail environment dramatically altered the digital self-publishing landscape, effectively paving the way for competing platforms (Kobo, Nook, iBooks, GooglePlay) and today’s vibrant—and, at times, crassly commercial—self-published fiction communities.As a result, the self-publishing market has experienced rapid growth: self-publishers now collectively hold the largest share of fiction sales within Amazon’s ebook categories, as much as 35% of the total market (Howey). Contrary to popular belief they do not reside entirely at the bottom of Amazon’s expansive catalogue either: at the time of writing, 11 of Amazon’s Top 50 Bestsellers were self-published and the median estimated monthly revenue generated by these ‘indie’ books was $43,000 USD / month (per author) on the American site alone (KindleSpy).This international publishing market now proffers authors running the gamut of commercial uptake, from millionaire successes like romance writer H.M. Ward and thriller author Mark Dawson, through to the 19% of self-published authors who listed their annual royalty income as $0 per annum (Weinberg). Their overall market share remains small—as little as 1.8% of trade publishing in the US as a whole (McIlroy 4)—but the high end of this lucrative slice is particularly dynamic: science fiction author Michael Anderle (and 20Books2017 keynote) is on-track to become a seven-figure author in his second year of publishing (based on Amazon sales ranking data), thriller author Mark Dawson has sold over 300,000 copies of his self-published Milton series in 3 years (McGregor), and a slew of similar authors have recently attained New York Times and US Today bestseller status.To date, there is not a broad range of scholarship investigating the operational logics of self-published fiction. Timothy Laquintano’s recent Mass Authorship and the Rise of Self-Publishing (2016) is a notable exception, drawing self-publishing into historical debates surrounding intellectual property, the future of the book and digital abundance. The more empirical portions of Mass Authorship—taken from activity between 2011 to 2015—directly informs this research and his chapter on Amazon (Chapter 4) could be read as a more macro companion to my findings below; taken together and compared they illustrate just how fast-moving the market is. Nick Levey’s work on ‘post-press’ literature and its inherent risks (and discourses of cultural capitol) also informs my thesis here.In addition to which, there is scholarship centred on publishing more generally that also touches on self-published writers as a category of practitioner (see Baverstock and Steinitz, Haughland, Thomlinson and Bélanger). Most of this later work focuses almost entirely on the finished product, usually situating self-publishing as directly oppositional to traditional publishing, and thus subordinating it.In this paper, I hope to outline how the self-publishers I’ve observed have enacted various tactical approaches that specifically strive to tame their chaotic marketplace, and to indicate—through one case study (Amazon exclusivity)—a site of production and resistance where they have occasionally succeeded. Their approach is one that values information sharing and an open-source approach to book-selling and writing craft, ideologies drawn more from the tech / start-up world than commercial book industry described by Thompson (10). It is a space deeply informed by the virtual nature of its major platforms and as such, I argue its relation to the world of traditional publishing—and its representation within the traditional book industry—are tenuous, despite the central role of authorship and books.Making the Virtual Self-Publishing SceneWithin the study of popular music, the use of Barry Shank and Will Straw’s ‘scene’ concept has been an essential tool for uncovering and mapping independent/DIY creative practice. The term scene, defined by Straw as cultural space, is primarily interested in how cultural phenomena articulates or announces itself. A step beyond community, scene theorists are less concerned with examining an evolving history of practice (deemed essentialist) than they are concerned with focusing on the “making and remaking of alliances” as the crucial process whereby communal culture is formed, expressed and distributed (370).A scene’s spatial dimension—often categorized as local, translocal or virtual (see Bennett and Peterson)—demands attention be paid to hybridization, as a diversity of actors approach the same terrain from differing vantage points, with distinct motivations. As a research tool, scene can map action as the material existence of ideology. Thus, its particular usefulness is its ability to draw findings from diverse communities of practice.Drawing methodologies and approaches from Bourdieu’s field theory—a particularly resonant lens for examining cultural work—and de Certeau’s philosophies of space and circumstantial moves (“failed and successful attempts at redirection within a given terrain,” 375), scene focuses on articulation, the process whereby individual and communal activity becomes an observable or relatable or recordable phenomena.Within my previous work (see Bennett and Rogers, Rogers), I’ve used scene to map a variety of independent music-making practices and can see clear resemblances between independent music-making and the growing assemblage of writers within ebook self-publishing. The democratizing impulses espoused by self-publishers (the removal of gatekeepers as married to visions of a fiction/labour meritocracy) marry up quite neatly with the heady mix of separatism and entrepreneurialism inherent in Australian underground music.Self-publishers are typically older and typically more upfront about profit, but the communal interaction—the trade and gifting of support, resources and information—looks decidedly similar. Instead, the self-publishers appear different in one key regard: their scene-making is virtual in ways that far outstrip empirical examples drawn from popular music. 20Books2017 is only one of two conferences for this community thus far and represents one of the few occasions in which the community has met in any sort of organized way offline. For the most part, and in the day-to-day, self-publishing is a virtual scene.At present, the virtual space of self-published fiction is centralized around two digital platforms. Firstly, there is the online message board, of which two specific online destinations are key: the first is Kboards, a PHP-coded forum “devoted to all things Kindle” (Kboards) but including a huge author sub-board of self-published writers. The archive of this board amounts to almost two million posts spanning back to 2009. The second message board site is a collection of Facebook groups, of which the 10,000-strong membership of 20BooksTo50K is the most dominant; it is the originating home of 20Books2017.The other platform constituting the virtual scene of self-publishing is that of podcasting. While there are a number of high-profile static websites and blogs related to self-publishing (and an emerging community of vloggers), these pale in breadth and interaction when compared to podcasts such as The Creative Penn, The Self-Publishing Podcast, The Sell More Books Show, Rocking Self-Publishing (now defunct but archived) and The Self-Publishing Formula podcast. Statistical information on the distribution of these podcasts is unavailable but the circulation and online discussion of their content and the interrelation between the different shows and their hosts and guests all point to their currency within the scene.In short, if one is to learn about the business and craft production modes of self-publishing, one tends to discover and interact with one of these two platforms. The consensus best practice espoused on these boards and podcasts is the data set in which the remainder of this paper draws findings. I have spent the last two years embedded in these communities but for the purposes of this paper I will be drawing data exclusively from the public-facing Kboards, namely because it is the oldest, most established site, but also because all of the issues and discussion presented within this data have been cross-referenced across the different podcasts and boards. In fact, for a long period Kboards was so central to the scene that itself was often the topic of conversation elsewhere.Sticking in the Algorithm: The Best Practice of Fiction Self-PublishingSelf-publishing is a virtual scene because its “constellation of divergent interests and forces” (Shank, Preface, x) occur almost entirely online. This is not just a case of discussion, collaboration and discovery occurring online—as with the virtual layer of local and translocal music scenes—rather, the self-publishing community produces into the online space, almost exclusively. Its venues and distribution pathways are online and while its production mechanisms (writing) are still physical, there is an almost instantaneous and continuous interface with the online. These writers type and, increasingly dictate, their work into the virtual cloud, have it edited there (via in-text annotation) and from there the work is often designed, formatted, published, sold, marketed, reviewed and discussed online.In addition to which, a significant portion of these writers produce collaborative works, co-writing novels and co-editing them via cooperative apps. Teams of beta-readers (often fans) work on manuscripts pre-launch. Covers, blurbs, log lines, ad copy and novel openings are tested and reconfigured via crowd-sourced opinion. Seen here, the writing of the self-publishing scene is often explicitly commercial. But more to the fact, it never denies its direct co-relation with the mandates of online publishing. It is not traditional writing (it moves beyond authorship) and viewing these writers as emerging or unpublished or indeed, using the existing vernacular of literary writing practices, often fails to capture what it is they do.As the self-publishers write for the online space, Amazon forms a huge part of their thinking and working. The site sits at the heart of the practices under consideration here. Many of the authors drawn into this research are ‘wide’ in their online retail distribution, meaning they have books placed with Amazon’s online retail competitors. Yet the decision to go ‘wide’ or stay exclusive to Amazon — and the volume of discussion around this choice — is illustrative of how dominant the company remains in the scene. In fact, the example of Amazon exclusivity provides a valuable case-study.For self-publishers, Amazon exclusivity brings two stated and tangible benefits. The first relates to revenue diversification within Amazon, with exclusivity delivering an additional revenue stream in the form of Kindle Unlimited royalties. Kindle Unlimited (KU) is a subscription service for ebooks. Consumers pay a flat monthly fee ($13.99 AUD) for unlimited access to over a million Kindle titles. For a 300-page book, a full read-through of a novel under KU pays roughly the same royalty to authors as the sale of a $2.99 ebook, but only to Amazon-exclusive authors. If an exclusive book is particularly well suited to the KU audience, this can present authors with a very serious return.The second benefit of Amazon exclusivity is access to internal site merchandising; namely ‘Free Days’ where the book is given away (and can chart on the various ‘Top 100 Free’ leaderboards) and ‘Countdown Deals’ where a decreasing discount is staggered across a period (thus creating a type of scarcity).These two perks can prove particularly lucrative to individual authors. On Kboards, user Annie Jocoby (also writing as Rachel Sinclair) details her experiences with exclusivity:I have a legal thriller series that is all-in with KU [Kindle Unlimited], and I can honestly say that KU has been fantastic for visibility for that particular series. I put the books into KU in the first part of August, and I watched my rankings rise like crazy after I did that. They've stuck, too. If I weren't in KU, I doubt that they would still be sticking as well as they have. (anniejocoby)This is fairly typical of the positive responses to exclusivity, yet it incorporates a number of the more opaque benefits entangled with going exclusive to Amazon.First, there is ‘visibility.’ In self-publishing terms, ‘visibility’ refers almost exclusively to chart positions within Amazon. The myriad of charts — and how they function — is beyond the scope of this paper but they absolutely indicate — often dictate — the discoverability of a book online. These charts are the ‘front windows’ of Amazon, to use an analogy to brick-and-mortar bookstores. Books that chart well are actively being bought by customers and they are very often those benefiting from Amazon’s powerful recommendation algorithm, something that expands beyond the site into the company’s expansive customer email list. This brings us to the second point Jocoby mentions, the ‘sticking’ within the charts.There is a widely held belief that once a good book (read: free of errors, broadly entertaining, on genre) finds its way into the Amazon recommendation algorithm, it can remain there for long periods of time leading to a building success as sales beget sales, further boosting the book’s chart performance and reviews. There is also the belief among some authors that Kindle Unlimited books are actively favoured by this algorithm. The high-selling Amanda M. Lee noted a direct correlation:Rank is affected when people borrow your book [under KU]. Page reads don't play into it all. (Amanda M. Lee)Within the same thread, USA Today bestseller Annie Bellet elaborated:We tested this a bunch when KU 2.0 hit. A page read does zip for rank. A borrow, even with no pages read, is what prompts the rank change. Borrows are weighted exactly like sales from what we could tell, it doesn't matter if nobody opens the book ever. All borrows now are ghost borrows, of course, since we can't see them anymore, so it might look like pages are coming in and your rank is changing, but what is probably happening is someone borrowed your book around the same time, causing the rank jump. (Annie B)Whether this advantage is built into the algorithm in a (likely) attempt to favour exclusive authors, or by nature of KU books presenting at a lower price point, is unknown but there is anecdotal evidence that once a KU book gains traction, it can ‘stick’ within the charts for longer periods of time compared to non-exclusive titles.At the entrepreneurial end of the fiction self-publishing scene, Amazon is positioned at the very centre. To go wide—to follow vectors through the scene adjacent to Amazon — is to go around the commercial centre and its profits. Yet no one in this community remains unaffected by the strategic position of this site and the market it has either created or captured. Amazon’s institutional practices can be adopted by competitors (Kobo Plus is a version of KU) and the multitude of tactics authors use to promote their work all, in one shape or another, lead back to ‘circumstantial moves’ learned from Amazon or services that are aimed at promoting work sold there. Further to which, the sense of instability and risk engendered by such a dominant market player is felt everywhere.Some Closing Ideas on the Ideology of Self-PublishingSelf-publishing fiction remains tactical in the de Certeau sense of the term. It is responsive and ever-shifting, with a touch of communal complicity and what he calls la perruque (‘the wig’), a shorthand for resistance that presents itself as submission (25). The entrepreneurialism of self-published fiction trades off this sense of the tactical.Within the scene, Amazon bestseller charts aren’t as much markers of prestige as systems to be hacked. The choice between ‘wide’ and exclusive is only ever short-term; it is carefully scrutinised and the trade-offs and opportunities are monitored week-to-week and debated constantly online. Over time, the self-publishing scene has become expert at decoding Amazon’s monolithic Terms of Service, ever eager to find both advantage and risk as they attempt to lever the affordances of digital publishing against their own desire for profit and expression.This sense of mischief and slippage forms a big part of what self-publishing is. In contrast to traditional publishing—with its long lead times and physical real estate—self-publishing can’t help but appear fragile, wild and coarse. There is no other comparison possible.To survive in self-publishing is to survive outside the established book industry and to thrive within a new and far more uncertain market/space, one almost entirely without a mapped topology. Unlike the traditional publishing industry—very much a legacy, a “relatively stable” population group (Straw 373)—self-publishing cannot escape its otherness, not in the short term. Both its spatial coordinates and its pathways remain too fast-evolving in comparison to the referent of traditional publishing. In the short-to-medium term, I imagine it will remain at some cultural remove from traditional publishing, be it perceived as a threatening northern force or a speculative west.To see self-publishing in the present, I encourage scholars to step away from traditional publishing industry protocols and frameworks, to strive to see this new arena as the self-published authors themselves understand it (what Muggleton has referred to a “indigenous meaning” 13).Straw and Shank’s scene concept provides one possible conceptual framework for this shift in understanding as scene’s reliance on spatial considerations harbours an often underemphazised asset: it is a theory of orientation. At heart, it draws as much from de Certeau as Bourdieu and as such, the scene presented in this work is never complete or fixed. It is de Certeau’s city “shaped out of fragments of trajectories and alterations of spaces” (93). These scenes—be they musicians or authors—are only ever glimpsed and from a vantage point of close proximity. In short, it is one way out of the essentialisms that currently shroud self-published fiction as a craft, business and community of authors. The cultural space of self-publishing, to return Straw’s scene definition, is one that mirrors its own porous, online infrastructure, its own predominance in virtuality. Its pathways are coded together inside fast-moving media companies and these pathways are increasingly entwined within algorithmic processes of curation that promise meritocratization and disintermediation yet delivery systems that can be learned and manipulated.The agility to publish within these systems is the true skill-set required to self-publish fiction online. It traverses specific platforms and short-term eras. It is the core attribute of success in the scene. Everything else is secondary, including the content of the books produced. It is not the case that these books are of lesser literary quality or that their ever-growing abundance is threatening—this is the counter-argument so often presented by the traditional book industry—but more so that without entrepreneurial agility, the quality of the ebook goes undetermined as it sinks lower and lower into a distribution system that is so open it appears endless.ReferencesAmanda M.

The object of mapping is to produce a "correct" relational model of the terrain. Its assumptions are that the objects in the world to be mapped are real and objective, and that they enjoy an existence independent of the cartographer; that their reality can be expressed in mathematical terms; that systematic observation and measurement offer the only route to cartographic truth; and that this truth can be independently verified. -- J. B. Harley, "Deconstructing the Map" Cartography, in its pragmatic operation under these assumptions, avoids almost all of the problems of representation with which cultural studies is only too familiar. Maps are representations, and all representations, even "scientific" ones, are cultural signs rather than truths produced in an ideological vacuum. The notion that mathematics, as a tool of Renaissance rationality, allowed real, objective detachment from an object of study was slowly absorbed into the cartographic tradition of Europe about four hundred years ago. "From at least the seventeenth century onward there was an epistemic break in activities such as cartography and architecture, and European map makers increasingly promoted what we would describe today as a standard scientific model of knowledge and cognition" (Harley 234). This model, in its increasing reliance upon mathematics and mathematical probability, essentially avoids or denies the objection that scientific observation and interpretation, and especially the technological gaze of its lens, produce anything other than objective, "real" knowledge. Through a mathematical detachment from the world, aided by the gaze of the lens, we see not the world itself (which includes us in its unmappable flux) but the numbers, straight lines and generalisations (which do not) that modern maps, including photographs, must employ to give the world fixed form and meaning. We find this model of cartography most impressively represented today in NASA's Mars Global Surveyor (MGS) probe, not merely as a sign of the technical success of mathematics, but also of its conceptual failure to provide the "true" representations of terrain to which a truly scientific cartography must aspire. MGS's 1998 attempt to "solve" the controversy surrounding a particularly contentious area on Mars, called Cydonia, with newer, "truer" images of the infamous Face on Mars was, contrary to popular opinion, an unsuccessful one; unsuccessful because NASA failed to remove all reasonable doubt that the Face was a natural geological formation. Not that this was particularly evident from media coverage of the image's release and reception -- the maverick researchers who comprised the protest were given a less than admirable hearing at the trial. Australian headlines reported that the Mars "romantics" (The Australian) had their Face theory "scuttled" (Courier-Mail). Professor Stanley V. McDaniel was demoted to "Mr McDaniel" in the The Australian, someone who wants NASA to continue re-imaging Cydonia to document other nearby features because "he believes [they] are further evidence of a Martian civilisation" (6). Also misrepresented was the like-minded, if slightly more adventurous researcher, Richard Hoagland, author of the underground classic, The Monuments of Mars: A City on the Edge of Forever (1987). Hoagland carelessly became (in both newspapers) Richard "Hoaglund", "leader of the movement" that believes the face is a monument left in Mars's Cydonia region by an ancient civilisation. The Australian, in line with the rest of the Earth's media, was apparently closing the door on the annoyingly persistent research into the Artificial Origin at Cydonia (AOC) hypothesis, which actually "does not claim that there is proof of artificial features on Mars, but that the probability of there being artificial features is strong enough to make new high-resolution photographs a top priority for any future mission to that planet" (McDaniel 2). Rather than confront the hypothesis itself, The Australian merely reminded us that "despite the image being 10 times better than the Viking photograph [a simplified qualification of the imaging process], it seems that some people still want to dream about ancient Martians building huge monuments to themselves" (The Australian). Dr. Mark J. Carlotto, a widely published specialist in the areas of digital image processing, pattern recognition, and computer vision, apparently still wants to dream that dream. An advocate of the AOC hypothesis, he notes that close examination of the image reveals the formation to be rough and highly eroded. Many have therefore concluded that the Face is natural. But others contend that if the Face is artificial it must certainly be very old and highly eroded. Thus the question remains as to how to distinguish an eroded artificial feature from a natural one. (Carlotto) This interestingly portentous question is one which NASA's Jet Propulsion Laboratory (JPL) and their contracted image processors, the privately owned Malin Space Science Systems (MSSS) have been somewhat reluctant to confront since the image of the Face was first captured in Viking frame 35A72. NASA's inaugural public statement on the Cydonia issue, for example, was handled ... "clumsily". As McDaniel reports: Upon the discovery of the Face in July, 1976, a Viking Project Scientist held up Viking frame 35A72, containing the Face, and announced to the assembled press corps that in a picture taken a few hours later "it all went away; it was just the way the light fell on it" -- but with a significant omission: the alleged later photograph, in which the facial features were supposed to have disappeared, was not shown for comparison [because] the statement could not possibly have been true. Frame 35A72 was taken in the early evening at approximately 6pm local time (sun angle 10 degrees). The object was in darkness a few hours later; the spacecraft, with an orbital period of about 24 hours, was no longer in a position to re-photograph the site; nor would it return to the site for many more orbits to come. Thus NASA's first official response to this strange object was an inexplicable misstatement based upon an apparent impossibility. (McDaniel 11-2) Things did not improve from there. NASA was never able to produce the elusive second photograph, yet continued to maintain that it both existed and conclusively disproved that the landform in question could possibly be artificial. In May 1993 the paradox attracted the attention of Senator John Glenn, who received (along with at least ten other members of the House and the Senate) a copy of the NASA document "Information on NASA's Re-Photographing of the Cydonia Region of Mars", which still held that the Face disappeared in the different lighting angles of a separate frame, which it did not reference. Finally in June 1993, after another inquiry by Senator Dianne Feinstein, a revised draft was issued which omits reference to the mysterious "real" photograph of the Face (McDaniel 12-3). NASA's next attempt to re-image Mars, including Cydonia, was the Observer probe, which failed to observe much at all and was declared lost in space. In conjunction with the recent mysterious failure of the Russian Phobos probe, and NASA's constant public relations blunders, conspiracy theories abounded. Was there something lurking at the threshold? The answer came in 1998 through the MGS, from which MSSS had produced a newer, clearer, "truer" image of the contentious feature which seemed to confirm Dr. Michael Malin's own earlier (and strangely self-contradictory) evaluation of 35A72: "it's simply a funny looking hill -- there is nothing unusual about it" (McDaniel 55). The MGS image certainly appeared, at least to the "naked eye" perusing the newspaper, to be just that. The wilderness had been tamed, and the coals cooled, temporarily. We had melted the witch. But exorcisms are never "final". Although NASA had apparently relegated the monstrous Face back to the realm of nature, restoring it within the parameters of conventional geology, McDaniel, Carlotto and others have maintained that NASA's conclusions were drastically premature, noting, as mentioned previously, that if the Face is artificial it must certainly be very old and, considering the Martian environment, highly eroded (Carlotto). According to their independent research, detailed analysis of the MGS image (which NASA appears not to have commissioned), does not invalidate the hypothesis that the Face may be artificial. Rather, it confirms many of the facial features recorded by the Viking, provides further evidence for the formation's high degree of lateral symmetry, and illuminates more anomalous internal detail (Carlotto). The Face on Mars, like the classical monsters of history, will not die easily. Ironically, perusal of Carlotto's dense research is an entry into the latent but undeniable plasticity of numbers, which itself is the quality of the monster that haunts modern cartographic representation. Mathematics, in almost every field of application, is finding it increasingly difficult to keep its disordering unknowns at bay. Geographer Erol Torun, for example, examined the angles formed by the facets of the two-mile long "D & M pyramid" (named after its discoverers, Vincent DiPietro and Gregory Molenaar). As Brian O'Leary writes, he subsequently found that the ratios between the five principal angles at the pyramid apex "express the universal mathematical constants of the square roots of 2,3,5,6, e, and pi ... . These constants should be known by any civilisation possessing Egyptian level technology (or greater) ... . The constants themselves are universal because they exist regardless of the number of the base being used". Regarding the other angles, Torun continued to find mathematically significant numbers "no matter how I looked at the object" (O'Leary 210). As the Cydonia controversy seems to clearly demonstrate, rather than revealing obvious, fixed truths about the world, mathematics and the observational tools they inspire require us to learn to see an approximation of the object they construct and represent as "real". We are thus compelled to draw the Other closer, but not "really", through the technological gaze of the artificial lens, a gaze that works to mask its own latent epistemic crisis. Indeed, this very compulsion inspired the growth of popular microscopy in the mid-eighteenth century, which required a new mode of seeing that could only very generously be termed "observation". Captain Basil Hall vividly recalls a meeting of the Geological Society, when a bottle was produced which was said to contain certain zoophytes. It was handed round, in the first instance, among the initiated on the foremost benches, who commented freely with one another on the forms of the animals in the fluid; but, when it came to our hands, we could discover nothing in the bottle but the most limpid fluid, -- without any trace, so far as our optics could make out, of animals dead or alive, the whole appearing absolutely transparent. The surprise of the ignorant at seeing nothing was only equal to that of the learned who saw so much to admire; nor was it till we were specifically instructed what we were to look for, and the shape, size, and general aspect of the zoophytes pointed out, that our understandings began to co-operate with our eyesight in peopling the fluid, which, up to that moment, had seemed perfectly uninhabited. The wonder then was, how we could possibly have omitted seeing objects now so palpable. (Mantell 8) Indeed, as Harley indicates, the relationship between the geographic and microscopic gaze is fundamental to the modern cartographic tradition. He cites Monmonier and Schnell's Map Appreciation (1988) as a recent example: Geography thrives on cartographic generalisation. The map is to the geographer what the microscope is to the microbiologist, for the ability to shrink the earth and generalise about it ... the microbiologist must choose a suitable objective lens, and the geographer must select a map scale appropriate to both the phenomenon in question and the "regional laboratory" in which the geographer is studying it. (in Harley 245) Importantly for this discussion, through both microscopy and cartography, "photography has also played a large role in twentieth-century ethnological representation", writes James Duncan. What better way to assert the primacy of the visual, produce a "true" representation of the place in question and establish presence than through the use of photography? But the mimetic claims of photography can also be called into question. A camera is a machine constructed to produce an image based upon artificial perspective. Only if one accepts the claims of the naturalness of Renaissance artificial perspective can we accept photography as a mimetic representation of the world. Such claims can be cast in doubt, for example, by the failure of peoples unfamiliar with photographs to be able to "read" them. (43) At the end of the day, though, it all may have more to do with down-to-earth economics than Martian "geopolitics". For many researchers, McDaniel among them, NASA's evasive treatment of the Face and surrounding features (variously labelled the Tholus, the D&M pyramid, the Fort, and the City Square) suggests a cover-up. Specifically, a cover-up of NASA's own inexplicable lack of investigation into apparently artificial structures on the Martian surface. Since the Jet Propulsion Laboratory's data imaging is contracted to a private company legally unaccountable to the public, McDaniel has confronted the somewhat disheartening possibility that financial motives may be obscuring investigation into what seem to be the most intriguing features of the Martian surface. He "does not personally believe in the conspiracy theory", but simply suggests that the Cydonia controversy may demonstrate that the financial interests of Malin Space Science Systems have assumed higher priority than the search for extraterrestrial artefacts: The contract for the Mars Observer (now MGS) involved close to 10 million dollars for Malin Space Science Systems ... . If it became clear that the probability of artificial structures on Mars is very high [or even that such a probability existed], it seems the focus of investigation would shift radically. The emphasis would fall to an accelerated manned mission to Mars. Archaeologists and perhaps biologists would assume an increasingly important role. It would be the manned mission (Johnson Space Flight Centre), not JPL, that takes the driver's seat. (McDaniel 1999) In other words, by producing results which indicated that the Cydonia region was worthy of closer attention, MSSS would jeopardise the future of its own multi-million dollar contract with NASA's Jet Propulsion Laboratory -- hardly a wise business venture, regardless of their geopolitical stance. But whatever the "true" source of the Martian controversy (it is, after all, the mythic planet of war), it seems undeniable that the Face on Mars is at once both an appropriately postmodern enigma and a genuine cartographic anomaly. For we find embodied within its monstrous form (through the lens), the message that our gaze is destined to be returned by ourselves. From the stars to the quarks, "we" seem to forever inhabit the very wilderness our technological gaze functions to both distance and draw closer; to abject. References Berland, Jody.

Management of desert grasslands requires rapid, low technology, coarse assessment methods that provide a triage-like prioritization for the manager. Such approaches necessitate the ability to quickly and effectively identify coarse-scale plant communities that provide guidance for this prioritization. Complex, computer intensive digital image classification of Landsat TM data, while marginally successful, requires time, equipment, and expertise not always available in such environments. This study identifies landform boundaries in the Armendaris Ranch, New Mexico by visual inspection of Landsat-7 Enhanced Thematic Mapper imagery and topographic maps using traditional photoreconnaissance techniques. Employing predetermined hierarchical landform classifications, it was possible to map plant communities using ecological relationships that exist between the general physiographic and vegetation settings in the area and representative geomorphic landform-mapping units. The authors’ field work verified the plant community map using a random walk approach and visual inspection. This synthetic expert opinion-based approach proved successful and is repeatable in other arid rangeland settings.
