Abstract:

American urban neighborhoods are a patchwork; the spatial arrangement of types is a reflection of the dominant transportation technology at the time of their development. The earliest suburban areas were made accessible by fixed route systems such as the electric streetcar, followed by the widespread adoption of the automobile; each transportation epoch resulted in characteristic patterns of land use. This study uses aerial photographic coverage of Portland, Oregon from the years 1925, 1936, and 1945, a time of decline for the once popular trolley lines and dramatic increase in automobile usage, to monitor change within the residential areas of Portland's east side over a twenty year period. Classic economic models of the time acknowledged transportation as a force shaping the city; modem ideas in urban planning such as Traditional Neighborhood Design and Transit Oriented Development look to pre-automobile urban form as a means to reduce automobile use and its negative implications. This study uses variables of housing density and street connectivity derived from the aerial photography; the measured values of these variables are then considered for their spatial and temporal distribution using statistical comparisons. The results are compared to ideas within the urban models and current thinking about urban morphology. While generally consistent with the expected patterns, deviations and differences between the two variables are considered for their implications. Models offer a simplified version of the growth of American cities, considering only a few of the many aspects of a dynamic environment. By isolating on these variables of density and connectivity, a greater understanding of their role in arriving at the modem residential urban environment may be reached, and this understanding can add to the discourse in current planning debates.

Abstract:

Aerial photography was used to determine the land use in a test area of the Nigerian savanna in 1950 and 1972. Changes in land use were determined and correlated with accessibility, appropriate low technology methods being used to make it easy to extend the investigation to other areas without incurring great expense. A test area of 750 sq km was chosen located in Kaduna State of Nigeria. The geography of the area is summarised together with the local knowledge which is essential for accurate photo interpretation. A land use classification was devised and tested for use with medium scale aerial photography of the savanna. The two sets of aerial photography at 1:25 000 scale were sampled using systematic dot grids. A dot density of 8 1/2 dots per sq km was calculated to give an acceptable estimate of land use. Problems of interpretation included gradation between categories, sample position uncertainty and personal bias. The results showed that in 22 years the amount of cultivated land in the test area had doubled while there had been a corresponding decrease in the amount of uncultivated land particularly woodland. The intensity of land use had generally increased. The distribution of land use changes was analysed and correlated with accessibility. Highly significant correlations were found for 1972 which had not existed in 1950. Changes in land use could also be correlated with accessibility. It was concluded that in the 22 year test period there had been intensification of land use, movement of human activity towards the main road, and a decrease in natural vegetation particularly close to the road. The classification of land use and the dot grid method of survey were shown to be applicable to a savanna test area.

Abstract:

Historic land uses impose discernable legacy effects that may influence ecosystem function, a concern of particular importance in actively managed landscapes. In recent history (ca. 150 years) tree and shrub abundance has increased at the expense of native grasses in savannas and grasslands. The magnitude and patterns of change are spatially heterogeneous, highlighting the need for analytical approaches spanning multiple spatial scales, from individual plants to patches to landscapes. The overarching goal of this dissertation was to explore long-term dynamics associated with woody plant encroachment with aerial photography and field studies to examine cover, density, soils and land use history at the Santa Rita Experimental Range.The first study characterized patterns in woody cover change on contrasting soils over 60 years using aerial photography. Woody patch dynamics revealed encroachment and stabilization phases in woody plant proliferation. Soil properties reflected the rate at which uplands reached a dynamic equilibrium, but not the endpoint (ca. 35% cover). Fluctuations around dynamic equilibrium reflected net change in patch growth and acquiescence combined with colonization and mortality. Efforts to characterize changes in land cover will require patch-based assessments beyond coarse estimates of percent cover.The second study capitalized on historic field measurements of shrub canopies to validate estimates of shrub cover derived from the earliest aerial photography, quantified detection limitations of 1936 aerial photographs for mapping shrub cover, assessed species-specific contributions to percent cover, and translated detection limitations to proportions of velvet mesquite (Prosopis velutina var Woot.) biomass missed with 1930s aerial photography.The third study was a field-based approach investigating how livestock grazing influenced mesquite cover, density, biomass, and stand structure over 74 years. The study supplemented traditional statistical analysis of grazing effects with methods quantifying spatial autocorrelation structure of mesquite density by grazing treatment. The outcome re-affirmed the supposition that mesquite cover may be dynamically stable at ca 30%, and revealed that livestock grazing slowed the shrub encroachment process from 1932 to 2006, counter to expectation. Results indicate that shrub growth trajectories persist long-term. Overall, this work affirms the importance of land use legacies and long-term perspectives in rangeland shrub dynamics.

Abstract:

Over the past several decades, naturally occurring populations of Fraser fir (Abies fraseri) in the Black Mountains of North Carolina have been heavily impacted by both direct and indirect anthropogenic disturbances, including logging and logging- associated fires, and high mortality rates due to the introduction of the exotic insect, balsam woolly adelgid (BWA) (Adelges piceae). The decline in Fraser fir is particularly concern because it serves as a foundation species within the spruce-fir forests of the Southern Appalachian Mountains. Our objectives for this research were to 1) use current stand structure to infer whether Fraser fir trees are experiencing a cycle of regeneration-mortality that will lead to eventual decline of the population, 2) determine what role, if any, the site-specific geographic variables of slope, elevation, aspect, and land use history have on stand structure, mortality, and BWA infestation level, and 3) analyze repeat aerial photography to examine broad trends of spruce-fir forest cover change caused by anthropogenic disturbance and the BWA. In order to understand stand structure, mortality, and infestation levels, we conducted detailed field surveys of Fraser fir trees throughout the Black Mountains using 44, fixed-radius circular sampling plots. These plots were placed throughout a series of aspects, elevations, and disturbance types in order to understand geographic variability among these variables. An analysis of 4 repeat aerial photographs and corroborating ground photographs revealed broad spatio-temporal trends of spruce-fir regeneration and mortality from 1954 to 2006. Our results indicate that Fraser fir stands at higher elevations are currently in a state of recovery; whereas stands at lower elevations appear to be more susceptible to BWA-induced mortality. Changes in forest cover area from 1954 to 2006 were influenced greatly by direct and indirect anthropogenic disturbance. Our results call attention to the significant impact that direct and indirect anthropogenic disturbance has had on Fraser fir stand structure, but also provide evidence for the ability of an imperiled ecosystem to recover from high rates of insect caused mortality.

Abstract

Since 1999, Very High spatial Resolution satellite data (Ikonos-2, QuickBird and OrbView-3) represent the surface of the Earth with more detail. However, information extraction by multispectral pixel-based classification proves to have become more complex owing to the internal variability increase in the land-cover units and to the weakness of spectral resolution.

Therefore, one possibility is to consider the internal spectral variability of land-cover classes as a valuable source of spatial information that can be used as an additional clue in characterizing and identifying land cover. Moreover, the spatial resolution gap that existed between satellite images and aerial photographs has strongly decreased, and the features used in visual interpretation transposed to digital analysis (texture, morphology and context) can be used as additional information on top of spectral features for the land cover classification.

The difficulty of this approach is often to transpose the visual features to digital analysis.

To overcome this problem region-based classification could be used. Segmentation, before classification, produces regions that are more homogeneous in themselves than with nearby regions and represent discrete objects or areas in the image. Each region becomes then a unit analysis, which makes it possible to avoid much of the structural clutter and allows to measure and use a number of features on top of spectral features. These features can be the surface, the perimeter, the compactness, the degree and kind of texture. Segmentation is one of the only methods which ensures to measure the morphological features (surface, perimeter.) and the textural features on non-arbitrary neighbourhood. In the pixel-based methods, texture is calculated with mobile windows that smooth the boundaries between discrete land cover regions and create between-class texture. This between-class texture could cause an edge-effect in the classification.

In this context, our research focuses on the potential of land cover region-based classification of VHR satellite data through the study of the object extraction capacity of segmentation processes, and through the study of the relevance of region features for classifying the land-cover classes in different kinds of Belgian landscapes; always keeping in mind the parallel with the visual interpretation which remains the reference.

Firstly, the results of the assessment of four segmentation algorithms belonging to the two main segmentation categories (contour- and region-based segmentation methods) show that the contour detection methods are sensitive to local variability, which is precisely the problem that we want to overcome. Then, a pre-processing like a filter may be used, at the risk of losing a part of the information. The “region-growing” segmentation that uses the local variability in the segmentation process appears to be the best compromise for the segmentation of different kinds of landscape.

Secondly, the features calculated thanks to segmentation seem to be relevant to identify some land-cover classes in urban/sub-urban and rural areas. These relevant features are of the same type as the features selected visually, which shows that the region-based classification gets close to the visual interpretation.

The research shows the real usefulness of region-based classification in order to classify the land cover with VHR satellite data. Even in some cases where the features calculated thanks to the segmentation prove to be useless, the region-based classification has other advantages. Working with regions instead of pixels allows to avoid the salt-and-pepper effect and makes the GIS integration easier.

The research also highlights some problems that are independent from the region-based classification and are recursive in VHR satellite data, like shadows and the spatial resolution weakness for identifying some land-cover classes.

Résumé

Depuis 1999, les données satellitaires à très haute résolution spatiale (IKONOS-2, QuickBird and OrbView-3) représentent la surface de la terre avec plus de détail. Cependant, l’extraction d’information par une classification multispectrale par pixel devient plus complexe en raison de l’augmentation de la variabilité spectrale dans les unités d’occupation du sol et du manque de résolution spectrale de ces données. Cependant, une possibilité est de considérer cette variabilité spectrale comme une information spatiale utile pouvant être utilisée comme une information complémentaire dans la caractérisation de l’occupation du sol. De plus, de part la diminution de la différence de résolution spatiale qui existait entre les photographies aériennes et les images satellitaires, les caractéristiques (attributs) utilisées en interprétation visuelle transposées à l’analyse digitale (texture, morphologie and contexte) peuvent être utilisées comme information complémentaire en plus de l’information spectrale pour la classification de l’occupation du sol.

La difficulté de cette approche est la transposition des caractéristiques visuelles à l’analyse digitale. Pour résoudre ce problème la classification par région pourrait être utilisée. La segmentation, avant la classification, produit des régions qui sont plus homogène en elles-mêmes qu’avec les régions voisines et qui représentent des objets ou des aires dans l’image. Chaque région devient alors une unité d’analyse qui permet l’élimination de l’effet « poivre et sel » et permet de mesurer et d’utiliser de nombreuses caractéristiques en plus des caractéristiques spectrales. Ces caractéristiques peuvent être la surface, le périmètre, la compacité, la texture. La segmentation est une des seules méthodes qui permet le calcul des caractéristiques morphologiques (surface, périmètre, …) et des caractéristiques texturales sur un voisinage non-arbitraire. Avec les méthodes de classification par pixel, la texture est calculée avec des fenêtres mobiles qui lissent les limites entre les régions d’occupation du sol et créent une texture interclasse. Cette texture interclasse peut alors causer un effet de bord dans le résultat de la classification.

Dans ce contexte, la recherche s’est focalisée sur l’étude du potentiel de la classification par région de l’occupation du sol avec des images satellitaires à très haute résolution spatiale. Ce potentiel a été étudié par l’intermédiaire de l’étude des capacités d’extraction d’objet de la segmentation et par l’intermédiaire de l’étude de la pertinence des caractéristiques des régions pour la classification de l’occupation du sol dans différents paysages belges tant urbains que ruraux.

Abstract:

This doctoral thesis examines the history of the Iraqw’ar Da/aw area in the Mbulu Highlands of northern Tanzania. Since the late nineteenth century this area has been known for its intensive cultivation, and referred to as an “island” within a matrix of less intensive land use. The conventional explanation for its characteristics has been high population densities resulting from the prevention of expansion by hostility from surrounding pastoral groups, leading to a siegelike situation. Drawing on an intensive programme of interviews, detailed field mapping and studies of aerial photographs, early travellers’ accounts and landscape photographs, this study challenges that explanation. The study concludes that the process of agricultural intensification has largely been its own driving force, based on self-reinforcing processes of change, and not a consequence of land scarcity.

Abstract:

An automated procedure was developed to identify and extract confined poultry facilities from color 35-mm slide imagery collected by the United States Department of Agriculture/Farm Service Agency (USDA/FSA). The imagery is used by the USDA/FSA to monitor compliance with various farm support programs and to determine crop production acreage within a given county. The imagery is generally available for all counties within the state on an annual basis. The imagery, however, is not flown to rigid specifications as flight height, direction, and overlap can vary significantly. The USDA/FSA attempts to collect imagery with reasonably clear skies, as visual interpretations could be drastically impacted by cloudiness. The goal of this study was to develop procedures to effectively utilize this imagery base to identify and extract poultry facilities using automated techniques based on image processing and GIS. The procedure involved pre-screening the slides to determine coverage, geopositioning to USGS quadrangle base, color scanning to convert slide image to a digital format and archiving each data file with a naming convention that would allow rapid retrieval in later analysis. Image processing techniques were developed for identifying poultry facilities based on spectral characteristics. GIS tools were used to select poultry facilities from an array of features with similar spectral characteristics. A training data set was selected from which the spectral characteristics of poultry facilities were analyzed and compared with background conditions. Poultry facilities were found to have distinguishable characteristics. Descriptive statistics were used to define the range of spectral characteristics encompassing poultry facilities. Thresholding analyses were then utilized to eliminate all image features with spectral characteristics outside of this range. Additional analyses were made to remove noise in the spectral image due to the sun angle, line of sight of camera, variation in roof reflectance due to rust and/or aging, shading by trees, etc. A primary objective in these analyses was to enhance the spectral characteristics for the poultry facility while, at the same time, retaining physical characteristics, i.e. the spectral characteristic is represented by a single blue color with a high brightness value. The techniques developed to achieve a single blue color involved the use of Principal Component Analysis (PCA) on the red color band followed by RGB to Hue and RGB to Saturation analyses on the red and green color bands, respectively, from the resulting image. The features remaining from this series of analyses were converted into polygons (shape file) using ArcView GIS, which was then used to calculate the area and perimeter of each polygon. The parameters utilized to describe the shape of a poultry house included width, length, compactness, length-width ratio, and polygon centroid analysis. Poultry facilities were found to have an average width of approximately 12.6m with a low standard deviation indicating that the widths of all houses were very similar. The length of poultry facilities ranged from 63m to 261m with and average length of 149m. The compactness parameter, which also is related to length and width, ranged from 30 to 130 with a mean value of approximately 57. The shape parameters were used by ArcView GIS to identify polygons that represent poultry facilities. The order of selection was found to be compactness followed by length-width ratio and polygon centroid analysis. A data set that included thirty 35-mm slide images randomly selected from the Rockingham County data set, which contained over 2000 slides, was used to evaluate the automated procedure. The slides contained 182 poultry houses previously identified through manual procedures. Seven facilities were missed and 175 were correctly identified. Ninety-seven percent (97%) of existing poultry facilities were correctly identified which compares favorably with the 97 % accuracy resulted by manual procedures. . The manual procedure described by Mostaghimi, et. al.(1999) only gave the center coordinates for each poultry facility. The automated procedure not only gives the center coordinate for each poultry building but also gives estimates for geometric parameters area, length and width along with an estimate of the capacity of building (i.e. number of birds), and waste load generated by birds including nutrient and bacteria content. The nutrient and bacteria load generated by each poultry facility is important information for conducting TMDL studies currently being developed for impaired Virginia streams. The information is expected to be very helpful to consultants and state agencies conducting the studies. Agricultural support agencies such as USDA/NRCS and USDA/FSA, Extension Service, consultants, etc. will find the information very helpful in the development of implementation plans designed to meet TMDL target water quality goals. The data also should be useful to Water Authorities for selection of appropriate treatment of water supplies and to county and local government jurisdictions for developing policies to minimize the degradation of water supplies.

Abstract:

The monitoring of ecological condition of grasslands ecosystems in the European Alps is a main issue for mountain regions, since the abandonment of traditional and sustainable management practices has exposed grassland habitat to significant impacts in a context of global environmental change. The present research project was focused in assessment of the state of permanent meadows in the lowlands of Valtellina Valley (80 km2), Italian Alps, during the timeframe 1980-2000. In specific, it quantified the land use/land cover changes and identified main drivers behind permanent meadows loss; characterized the relationship between biodiversity in the meadows and the spatial-environmental conditions in the landscape and by last evaluated the use of satellite remote sensing data for fast change detection in landscape. To achieve such aims, the research project was organized in three different approaches presented in the four chapters of this thesis. Concerning the quantification of the land use/land cover and identification of main drivers behind permanent meadows loss, the results show a strong decrease in meadows (-18.5%) in a context of agricultural land decrease and human settlements increase. This was the land cover type with highest loss and conversion rate during the study period. Meadows were converted to human settlements (urban, industrial and roads), other agriculture uses (cultivation, orchard, vineyard), bushland and uncultivated land. Meadows loss occurred mainly in soils with good land capability, low slope, exposed to south and in proximity of roads, urban settlements and bushland. Densities of urban, industrial and bushland and land capability were the only significant drivers for meadows loss, while distance to meadow edge, meadows density, distance to roads and soil degradation were the only significant drivers for meadows preservation. Concerning the characterization of the relationship between biodiversity in the meadows and the spatial-environmental conditions in the landscape, the results evidenced that species richness and Shannon indices were best explained by regressive models including changes occurred in spatial environmental heterogeneity from 1980 to 2000. Species richness was negatively related to strong decrease in meadows habitat area and recent urban area, while Shannon index was positively related to the increase in landscape diversity. In contrast, species evenness was better explained by regressive model including recent spatial environmental heterogeneity and positively related to increase ineastness in the study area, and negatively affected both by the area of woody and soil pH (KCl). Concerning the evaluation of the use of satellite remotely sensing data for land cover mapping and change detection in landscape, the results show that the hybrid approach for land cover classification based of Landsat imagery was highly accurate. Image differencing is the technique which best detect changes in landscape as well as in urban, meadow and bush land. The accuracy of change detection was moderate. This thesis concludes that the conflict by land in locations densely occupied by other land cover types with good land capability is the major threat to meadows and avoidance of fragmentation may be a good strategy for its preservation. The meadows habitat needs a well-designed landscape and farming planning, which should account the economic value of the ecosystem services provided by this habitat. In addition, to conserve plant diversity in meadows it is necessary to avoid loss of meadows habitat, maintain landscape diversity and execute a sustainable meadow management. Remotely sensed imagery can be a reliable source of information for alps, although particular attention should be made to the image pre-processing and classification, as well as, to minimize topography effects in spectral information.

Abstract:

Bayesian estimates of gross cubic- foot volume per acre were computed for four stand types (plantation pine, natural pine. hardwood. and mixed wood stands) using aerial photo volume tables as the prior information source. Aerial photographs provided a reliable source of information even though most photographs were nearly five years old. For a given level of precision within a particular stand, Bayesian methods reduced the required field sample size up to 50% using all or half of the prior information available. Those priors which utilized a regression or a regression/topographic correction in the estimation of photo heights required less field information for the given precision level than those priors which used uncorrected or topographic corrected photo heights. In order to obtain meaningful gains in sample size reduction corrections to the estimated photo heights should be made. Although the uncorrected prior produced generally less biased estimates. the reduction in sample size was not as large as that observed using other prior types. Greater gains were attributed to the better accuracy of the prior distribution. Although Bayesian methods are biased, it appeared that these methods tempered severely biased prior distributions. In the hardwood stand for example, the average bias present in the photo volume data amounted to -140%. After combining the prior with the field sample, the greatest average bias was -50%. Bayesian methods performed better than the traditional estimation methods in terms of precision. In a one to one comparison. the Bayes standard error was consistently less than its non-Bayes counterpart. The one exception to this trend was the regression prior from the hardwood stand. The poor performance of the prior was due to the weak height regression correction equation. Modal priors utilized were not subject to the extreme input values for prior distribution development as their conservative empirical prior counterparts were. Less overall variation was observed 1n the estimated values. Under the conditions for mode selection set forth in this project, modal priors provided another good source of prior information.

Abstract:

Remote sensing technologies are used to assist in the mapping and monitoring of land cover in space and time. The European Space Agency’s (ESA) upcoming Sentinel-2 MultiSpectral Instrument (MSI) to be launched in 2013 has improved spatial and spectral properties compared to the current large-swath medium-resolution satellite sensors. Prior to the deployment of future sensors it is important to simulate and test the sensor data to evaluate the sensor's potential performance in producing the existing data products and develop new algorithms. This study simulated Sentinel-2 MSI data from airborne hyperspectral data over an agriculture area in northern Alberta, Canada. The standard Sentinel-2 MSI land-cover product was evaluated by comparing it to one created from the standard Landsat 5 TM and SPOT 5 HRV data products. Furthermore the standard Sentinel-2 MSI water column content band configuration and algorithm was evaluated for atmospheric correction purposes.

Abstract:

The coastal zone is a highly dynamic entity both spatially and temporally and when shoreline changes (and in particular retreat) occur on a hmnan time-scale, measurement of the rate of change becomes a pressing issue. This dynamism presents an excellent scenario for monitoring change using remote sensing techniques, and in the case of coastal sand dunes, where the requirement is to measure small scale changes such as erosion or accretion in the region of 10 or 20 m, aerial photography is the preferred source of remotely sensed data. The rapid developments in digital camera technology and real time satellite differential Global Positioning Systems have yielded new opportunities for mapping and monitoring environmental change when used with image processing and mapping software and state-of-the-art digital photogrammetric workstations. Despite the progress in digital technologies, however, there is still considerable lack of awareness on the part of potential users, and it is in response to this that the processing chain for data collection through to orthophoto production described here has been developed. This study explores the major issues that affect quality, mission logistics and cost and will demonstrate the methodology and application of digital techniques for producing georectified imagery and contoured orthophoto maps of coastal environments. This will be achieved through a series of case studies of dynamic dune environments in south-west England and France. Digital imagery was captured using a colour infrared Aerial Digital Photographic System and ground control was collected using differential Global Positioning Systems. This study seeks to assess the application of this imagery to coastal dune monitoring, putting these new techniques within the grasp of coastal dune managers, enabling them to make use of digital imagery captured to different specifications depending on the accuracy requirement of the end product. The results indicate that this type of imagery and the techniques used can provide the dune manager with information which would otherwise be too costly or time consuming to acquire. 2D rectification of the imagery provided maps of dune retreat and accretion with errors in the region of± 1.5m, and rectification to a higher order using 3D photogrammetric correction provided 1 :5000 contoured orthophotographs with mean xy errors in the region of 2. 5 m and mean elevation errors in the region of 1.5m.

Abstract:

Interpretation of large-scale color infrared and color aerial photography can be a labor and cost-effective means for inventorying and monitoring rangelands while maintaining accuracy. Ground measurements of vegetation cover at Organ Pipe Cactus National Monument were taken in 1975 and 1984. Large-scale (1:1200) color and color infrared aerial photo estimates were compared to these ground measurements through regression and correlation to check photo accuracy. Relationships between photo estimates and ground measurements of total vegetation and shrub cover were strong when using either film type. Color infrared photo estimates corresponded better with ground measurements for both tree cover and cactus cover than color photo estimates. Large-scale aerial photography is also useful for determining some of the causes of vegetation change. Evidence gathered from both sets of photos suggested that vegetation change at OPCNM was largely the result of domestic livestock removal and short-term climatic fluctuations.

Abstract:

Diese Arbeit beschäftigt sich mit Aerial Rivers („luftgetragenen Flüssen“), den bevorzugten Wegen des Flusses von Feuchte in der Atmosphäre. Ziel ist es, die Voraussetzung für deren Integration in aktuelle Paradigmen der Wasserwirtschaft zu schaffen. Im Mittelpunkt der Arbeit stehen Amazonien und die angrenzenden Gebiete, also Regionen der Erde, in denen sich derzeit der Landnutzungswandel mit am schnellsten vollzieht. Aus theoretischer Sicht wird das Wissen über die Verbindung zwischen Aerial Rivers und Oberflächenflüssen erweitert. Mit Hilfe eines Algorithmus zur Verfolgung des atmosphärischen Feuchtigkeitstransports werden die Auswirkungen von entferntem Landnutzungswandel in Windrichtung auf die Niederschlagsmenge einer Zielregion quantifiziert. Die räumliche Heterogenität des Einflusses der gesamten Quellevapotranspirationsfläche (precipitationsehed) auf die/den empfangene/n Niederschlagsmenge/Oberflächenabfluss der Zielregion wird untersucht und führt zur Identifizierung der „Most Influential Precipitationshed“ (MIP), der für Managementzwecke relevantesten Teilfläche. Ein Aerial River-Managementbeispiel für Santa Cruz (Bolivien) zeigt, dass die strategische Wiederaufforstung im MIP sowohl die Niederschlagsmenge als auch den empfangenen Oberflächenabfluss erhöht und 22%-59% des zukünftigen Wasserbedarfszuwachses einer schnell wachsenden Stadt decken kann. Weiterhin werden sozio-technische Regime entlang von Aerial Rivers, die zu Extremereignissen wie Megadürren beitragen können, mit Hilfe der sozialwissenschaftlichen Methode der Multi-Level-Perspektive (MLP) untersucht. Ursachen wie Bodenpolitik und Marktinterventionen in Brasilien und Bolivien steuern weit entfernte kolumbianische Energieregime und deren Wandel. Aerial Rivers sind also zentral für zukünftiges Gewässermangement einschließlich Wasserkraft; ihr Management erfordert jedoch eine ganzheitliche Betrachtung der gesellschaftlichen Schnittstellen über administrative Grenzen und Sektoren hinweg.
Aerial rivers are the preferential pathways of moisture flows in the atmosphere. They connect the atmosphere, the water system, and the land system. This thesis aims to provide knowledge for integration of aerial rivers into management of these systems. It focuses on Amazonia and adjacent areas, which collectively experience some of the most rapid land use change on the planet. This thesis further develops three key aspects (theoretical, technical, and societal) of knowledge concerning aerial rivers. From a theoretical aspect, it advances the knowledge of connection between aerial rivers and surface rivers. Using a moisture tracking algorithm, the impact from upwind land use change via aerial rivers on target regions’ runoff reception is quantified. Spatial heterogeneity in the influence of the precipitationshed on runoff reception of the target region is found, implying a need to determine the most influential precipitationshed (MIP) for management purposes. From a technical aspect, the work demonstrates an aerial river management example for a rapidly growing city. It is shown that strategic reforestation in the MIP can increase both rainfall and runoff reception and secure 22%-59% of a rapidly growing city’s future water needs. Finally, the work explores the societal aspect of aerial river management. Socio-technical regimes along aerial rivers contributing to extreme events of mega-drought were traced through the social scientific method of multi-level perspective. It reveals that the source regimes such as land policy and market interventions in Brazil and Bolivia govern remote Colombian energy regimes and their transitions through aerial rivers. These findings show that aerial rivers are relevant and viable options for the development of future water resources - including hydropower - but their management will require a holistic consideration of the various societal interfaces as they cross jurisdictional boundaries and sectors.

Abstract:

The Image-based Change Estimation program (ICE) was developed by the US Forest Service Forest Inventory & Analysis (FIA) program and the Geospatial Technology Applications Center in response to the 2014 Farm Bill calling for more timely and accurate estimates of land cover and use change. ICE monitors change throughout the US on a state by state basis by assessing each FIA plot using high resolution imagery from two dates in time. In the western US, FIA measures 10% of the plots each year to report on status, trends, and sustainability of our Nation’s forests. However, this 10 year cycle misses disturbances because a temporal gap occurs from disturbance event to measurement. This study compares field- and image-based observations of land cover and use change to improve sampling procedures in Utah. Image-based data collected from 2011 and 2014 imagery and field-based plots measured between 2011 and 2016 are compared using three methods to compile the ICE data, termed hierarchical, majority, and point center, to determine a standardized system and better understand their relationships. Additionally, ICE change agents were compared with causes of tree mortality observed on FIA forest plots to assess how well ICE evaluates causes of change and the differences of change vs. mortality agents were explored by conducting a second review of the imagery to find trends in data discrepancies. This knowledge can help image interpreters better recognize and identify change.

Abstract:

Airborne multispectral video was evaluated as a tool for obtaining urban land cover information for hydrological simulations. Land cover data was obtained for a small urban watershed in Tucson, Arizona using four methods: multispectral aerial video (2 meter and 4 meter pixel resolution), National High Altitude Photography (NHAP), multispectral satellite imagery from Systeme Pour l'Observation de la Terre (SPOT), and by conventional survey. A semi-automated land cover classification produced four classes: vegetation, buildings, pavement, and bare soil. The land cover data from each classification was used as input to a runoff simulation model. Runoff values generate by each simulation were compared to observed runoff. A chi-square goodness-of-fit test indicated that SPOT produced landcover data most similar to the conventional classification. In the curve number model, the SPOT data produced simulated runoff values most similar to observed runoff.

Abstract:

Many calamities in history like hurricanes, tornado and flooding are proof to the large scale impact they cause to the life and economy. Computer simulation and GIS helps in modeling a real world scenario, which assists in evacuation planning, damage assessment, assistance and reconstruction. For achieving computer simulation and modeling there is a need for accurate classification of ground objects. One of the most significant aspects of this research is that it achieves improved classification for regions within which light detection and ranging (LiDAR) has low spatial resolution. This thesis describes a method for accurate classification of bare ground, water body, roads, vegetation, and structures using LiDAR data and aerial Infrared imagery. The most basic step for any terrain modeling application is filtering which is classification of ground and non-ground points. We present an integrated systematic method that makes classification of terrain and non-terrain points effective. Our filtering method uses the geometric feature of the triangle meshes created from LiDAR samples and calculate the confidence for every point. Geometric homogenous blocks and confidence are derived from TIN model and gridded LiDAR samples. The results from two representations are used in a classifier to determine if the block belongs ground or otherwise. Another important step is detection of water body, which is based on the LiDAR sample density of the region. Objects like tress and bare ground are characterized by the geometric features present in the LiDAR and the color features in the infrared imagery. These features are fed into a SVM classifier which detects bare-ground in the given region. Similarly trees are extracted using another trained SVM classifier. Once we obtain bare-grounds and trees, roads are extracted by removing the bare grounds. Structures are identified by the properties of non-ground segments. Experiments were conducted using LiDAR samples and Infrared imagery from the city of New Orleans. We evaluated the influence of different parameters to the classification. Water bodies were extracted successfully using density measures. Experiments showed that fusion of geometric properties and confidence levels resulted into efficient classification of ground and non-ground regions. Classification of vegetation using SVM was promising and effective using the features like height variation, HSV, angle etc. It is demonstrated that our methods successfully classified the region by using LiDAR data in a complex urban area with high-rise buildings.

Full text

Abstract:

Bush encroachment or the thickening of woody vegetation is a phenomenon occurring throughout savannas, which tends to be more pronounced in small protected areas. The consequences of bush encroachment are often negative for the conservation of biodiversity, for the promotion of tourism and the prevention of wildfires. Hence, effective monitoring of woody vegetation and the factors which influence its spread are essential. This is particularly the case for protected areas such as that of Bwabwata National Park (BNP) in north-east Namibia. With a complex land use history and different fire management approaches being adopted throughout the area, the effect of fire on woody vegetation in BNP is currently poorly understood. This study used a 20-year-old repeat photography monitoring project and satellite-based remote sensing products to explore woody cover dynamics in BNP. Results revealed that woody cover has increased by 13% since 1999 in BNP. Furthermore, the results show differences in the structure of woody vegetation. Repeated late dry season fires in the west of the park have driven an increasing dominance of 3m in eastern sections of the park. This influence of different fire regimes spatially across BNP, suggests that local fire management is a significant determinant of woody vegetation change. Woody vegetation change differs spatially across BNP due to frequent late dry season fires prevailing in the west and less frequent earlier season fires occurring in the east. Therefore, in order to reduce the mortality of woody species and conserve heterogenous height structure in the west, a reduction of frequent late dry season fires is required. Early dry season fires are shown to reduce the rate of increasing total woody cover change and, therefore, this fire management strategy arguably contributes towards the reduction of wildfire risk, conservation of biodiversity and promotion of tourism.

Abstract:

This thesis explores the forces of change in lives and landscapes that have altered the Lamosangu-to-Everest route in northeastern Nepal and shows how a transect in photographs and conversations across the east-central Himalaya allows us insight and a greater understanding into the processes and consequences of this change. Three forces of change over the last twenty-five years dominated discussions with local informants: the rise of the "People's War"-Nepal's Maoist Insurgency beginning in 1996; the Democratic Revolution of 1990; and dependence on tourism for livelihood after the establishment of Sagarmatha National Park in 1976. Understanding the cultural-historical context for these forces is necessary to understand the concerns of today's residents living along the Lamosangu-to-Mount Everest Base Camp transect. The visual and ethnographic evidence discussed in this thesis takes a larger role than strict analysis of conspicuous large-scale land use change and I hope the comparative 200 I images will be used as benchmarks for future research as well as for further exploration into the ways people and place have been represented.

Abstract:

Cette thèse, co-financée par l’ADEME, se place dans le cadre d’une collaboration entre le LIRIS et le Centre Léon Bérard autour de l’étude épidémiologique TESTIS. L’étude TESTIS vise à estimer l’impact des pesticides sur le développement de la tumeur germinale du cancer du testicule. Cette maladie ayant un temps de développement long, il est nécessaire d’avoir accès à des informations remontant jusqu’à la naissance des sujets considérés. Dans le cas de TESTIS, les sujets les plus âgés sont nés au début des années 1970. Afin de tenir compte des expositions résidentielles individuelles aux pesticides propagés par les vents, le Centre Léon Bérard a mis au point une métrique se basant sur l’occupation du sol autour des habitations. Malheureusement, aucune base de données d’occupation du sol avant 1990 n’est actuellement suffisamment précise pour être utilisée. Afin d’obtenir ces informations, les géomaticiens du Centre Léon Bérard sont chargés de photo-interpréter des images aériennes historiques en niveaux de gris. Ce processus manuel étant particulièrement long et fastidieux, l’utilisation de méthodes automatiques ou semi-automatiques a été suggérée. L’objectif de cette thèse est de développer des algorithmes pour aider les géomaticiens à obtenir des cartes d’occupation du sol en un temps raisonnable. Pour cela, nous nous sommes intéressés à l’utilisation de méthodes de classification de textures que nous avons intégrées au sein d’un logiciel d’aide à l’annotation. Celui-ci est actuellement utilisé dans le cadre de l’étude TESTIS. Nous nous sommes ensuite intéressés à la colorisation automatique et non-supervisée des images aériennes historiques afin de proposer une visualisation alternative aux géomaticiens. Ces travaux nous ont également menés à étudier l’intérêt des couleurs générées artificiellement pour la classification des données historiques. Enfin, nous avons cherché à améliorer les cartes d’occupation du sol générées par notre logiciel au travers de méthodes de post-traitement, ouvrant la voie au développement de chaines de traitements plus performantes
This thesis, co-funded by the ADEME, takes place in the context of a collaboration between the LIRIS laboratory and the Centre Léon Bérard as part of the TESTIS epidemiological study. The TESTIS study aims to estimate the impact of pesticides on the development of germ cell tumor of testicular cancer. As this disease has a long development time, it is necessary to have access to data dating back to the birth of the subjects. In the case of TESTIS, the oldest subjects were born in the early 1970s. In order to take into account individual residential exposures to pesticides spread by winds, the Centre Léon Bérard has developed a metric based on land use around dwellings. Unfortunately no land use database before 1990 is sufficiently accurate to be used. In order to obtain this information, the geomatics specialists at the Centre Léon Bérard are tasked with photo-interpreting historical aerial images in grayscale. This manual process is particularly long and tedious. Therefore, the use of automatic or semi-automatic methods has been suggested. The objective of this thesis is to develop algorithms to help geomatics specialists obtain land cover maps in a reasonable time. For that, we were interested in the use of texture classification methods that we have integrated into an annotation assistance software. This software is currently used in the TESTIS study. We then put our focus on the development of unsupervised colorization methods to provide alternative visualizations of the historical aerial images. This work also led us to study the interest of the artificially generated colors for land use classification. Finally, we sought to improve the land use maps generated by our software through post-processing methods, paving the way for the development of more efficient pipelines

Abstract:

Capturing Appalachia: Visualizing Coal, Culture and Ecology, draws on extensive ethnographic, archival, and ecographic research conducted across Appalachia between 2014-2016 to develop an empirically informed sociological image of the interactions between culture, geography, and industry. Of particular interest are the ways that extractive cultures in Appalachia are constructed and communicated, and so the project includes archival work researching historical images as well as fieldwork focused on the production of images. Drawing on the traditions of cultural and ‘green’ criminologies, geography, and critical ecotheory, concluding that the cultural, political, and ecological worlds of Appalachia exist in a dialectical relationship with one another, and that at the center of each is an intense cultural relationship with the region’s historic and contemporary capture (cultural, economic, and ecological) by resource extraction. These dialectical relationships are made clear in the visuality of Appalachia, with paradigms frequently challenged by the production of countervisual narratives in productions spanning photography, literature, cinema, and media. The project constitutes the first extensive empirical application of the suggestions of an emergent green-cultural criminology. This research contributes significantly to the existing theoretical literature on extractive cultures through the development and application of the concept of ‘capture’, which is employed in throughout and which constitutes a central concept the project. The concept of ‘regulatory capture’ informs much of the existing sociological literature on harmful industry. Expanding on the concept of ‘capture’, I consider the capture of Appalachian economies by a single industry (economic capture), the capture of cultural production by the dominant industry (cultural capture), the legal capture of material landscapes by industry (ecological capture), the visual-mechanical capture of images of ecology and culture (photographic capture), and finally, the capture of ecology and people by an emerging industry of incarceration (carceral capture).

Traditional forest inventory have to put in a lot of manpower and material resources to address weaknesses at the lowest cost, and new forest inventory methods based on remote sensing that have been an important issue. ADS40 airborne multispectral images are high-resolution aerial photographs that have been widely applied in forest inventory. In this study, we used the ADS40 airborne multispectral images to classify the land-use types of the Fourth Survey Forest Resource project. The use of High-Resolution Remote-Sensing (HRRS) imagery of classification is liable to cause heavy Salt-and-Pepper Noises; therefore, I chose object-oriented classification methods for ADS40 images to reduce material quantity of imageodesy. The results showed that the image segmentation scale 400 type was better than other image segmentation scales; hence image classification results of accuracy were used to compare pixel-base and object-base image classifications. The analysis determined that object-base image classification was better than pixel-base image classification. Each image information type was collected and used as the image of the superimposed images, and Maximum Likelihood Classification was used to compare different superimposed images of overall classification accuracy. The image group was elected of using Duncan statistical analysis that the result has 54.82% of overall classification accuracy, 0.4997 of overall kappa, and Kappa values were used to compare the two classification methods of Maximum Likelihood and the Knowledge-Based Classification to applicability of ADS40 images. In conclusion, Knowledge-Based Classification showed that the result had 78.20% of overall classification accuracy and 0.7597 of overall kappa statistics better than results of maximum likelihood classification.

This study determines and predicts multi-temporal Land-Use-Land-Cover Change (LULC) in a peripheral urban landscape over a 22 year period in relation to the study area‘s greenery. A change detection analysis using post classification Maximum Likelihood algorithm on three multispectral SPOT-4 images was used to determine land-cover transformation. To predict future land coverage, a Land-Cover Change Modeler (LCM) and a Markov Chain were used. Results show that between the year 2000-2006, 2006-2011 and 2000-2011 the study area experienced varied changes in the different LULCs. Built-up areas increased by 10.08%, 3.15% and 13.23% in 2000-2006, 2006-2011, and 2000-2011 respectively. Areas covered by thicket decreased by 0.59% in 2000-2006 but increased by 0.56%, 0.07% in 2006-2011 and 2000-2011 respectively. Forest land-cover increased by 2.59% in 2000-2006, 2.82% in 2006-2011, and 5.41% in 2000-2011. Grassland declined by 8.46% and 2.64% in 2000-2006 and 2000-2011 respectively while degraded grassland declined by 3.62%, 12.45% and 16.07% in 2000-2006, 2006-2011, and 2000-2011 respectively. Projection results indicate a consistent pattern of growth or decline to those experienced between 2000-2011. This study provides insight into LULC patterns within the eThekwini metro area and offers invaluable understanding of the transformation of the urban green spaces.

Abstract:

In order to manage the often highly dynamic urban landscapes, it is important to map different themes from time to time. This study made use of Geographical Information System and aerial photographs to determine LULC transformation in the eastern suburbs of Pietermaritzburg in KwaZulu-Natal, South Africa. Land use land cover maps for the eastern suburbs (Copesville, Eastwood, Raisethorpe and Willowton) for the years 1989 to 2009 were generated and transformations based on twelve LULCs determined. Results in this study showed that the most significant increase were in residential (formal and informal) and industrial LULCs while the most significant decrease were recorded in the cultivated and open LULC. Generally, results in this study further show that urban LULC attributed to human influx has been at the expense of internal open green spaces and peripheral cultivated and uncultivated lands. The study concludes that aerial photographs in concert with GIS are valuable tools in mapping rapidly changing urban landscapes.

It needs the information of land use intensity to control the growth of cities, such as building coverage ratio and building bulk ratio. It spends much manpower and time to get the information. The improving technology of digital photogrammetry and geographic information systems can assist investigate and collect the information. The objective of this research has been to analyze the land use intensity with assistance of geographic information systems and digital photogrammetry. Digital aerial photographs have been used to collect 3-D spatial information of research area. This information has been imported into a geographic information system. Building coverage ratio and building bulk ratio of whole research area could be established thereafter. The information collected by digital photogrammetry has also been investigated and checked in situ. The results have indicated that: 1.The ratios of both building coverage ratio and building bulk ratio to the original planned record have been of 1.1~1.2. 2.The most suitable height of each floor is 3.3m when calculating the floor number of building in the research area. 3.Digital aerial photographs could be very useful when the information of land use intensity was required.

ABSTRACT In recent years, natural resource has suffered from degrading by the frequent human activity around National park area that accelerate soil loss and slope instability. By the means of Aerial photogrammetry technique and the capability of GIS in handing large volume of dataset, there is an efficient way for sound environmental monitoring. Aerial photogrammetry and Satellite Image has become one of the important source for GIS database in forest surveying, land resources investigation, land use changes, and large area natural resources monitoring. In the past ,the detection of National Park was restricted by the mountain climate and her large territory. Most of the study was base on analog data from hands drawing or CAD-liked software. Coarse accuracy , low compatibility and the lack of updating capacity were the major obstacle of those data used for park management. This study extracted the information from Aerial photo ,Satellite Image and combined with GIS dataset for land cover change information. The goal was to achieve user friendly GUI interface which ease the accessibility for environmental managers. The result from different time span of this area served as a basic spatial and temporal information. When overlay with other ground information, such as cadastra map or land suitability map, this integrated system provides query, analysis, and statistic ability for environmental monitoring.

University of the Witwatersrand Masters Research Report History of Art 31 March 2015
Landscape representations in Western art have long stood as metaphors for power relations inscribed on the earth, encoding imperial aspirations, national identity, poetic and aesthetic experiences about humankind, nature and the environment. However, contemporary landscape imagery of large-scale industrial, and particularly mining sites, have come to signify, pre-dominantly through the medium of photography, meta-narratives that go beyond the political, economic, and environmental power relations historically endemic to landscape representation. Indeed, I suggest they constitute the formation of a sub-genre within the category of Landscape. Mining activities characterise extensive landscape interventions, often with catastrophic results both above and below ground. Perhaps a mined landscape more than any other, exemplifies not only the interwoven political and economic power relations inscribed upon the land, but also testifies to the underlying pathology of the land. Contemporary landscape studies cut across disciplines and go beyond the apprehension of surface, taking into account the geological as well social histories of land, and thus signal a shift in the aesthetic experience of land, both emotionally and intellectually, and consequently the way in which land is made visible. The visualisation of these land sites through imagery has precipitated an interface of aesthetic experience that simultaneously makes visible the politics symbolically encoded in the landscape itself, and the politics that impact viewership and reception. Nevertheless, accompanying the need to make visible those land sites hugely modified by mineral extraction, from both a historical and current perspective, is an unprecedented urgency that is weighted by a political anxiety over future implications of such land interventions. This anxiety is driven by the spectral nature of mined landscapes. Although monumental in scale, mined landscapes are often ‘not seen’, partly because they exist in restricted zones or are located underground, but often they are rendered invisible through a process of assimilation and naturalisation. A case in point has been the collective presence of mine dumps along Johannesburg’s southern periphery, and which, now in the process of being re-cycled, form the focus of my selected case study, an image by British photographer, Jason Larkin and titled Re-Mining Dump 20 (2012). By seeking to bring sites of mining activity into public consciousness, contemporary representations of mined landscapes also mediate current relations between humankind and the natural environment. As an agent of mediation, I propose that an image of a mined landscape functions as an interface. By situating Larkin’s image within a theoretical framework motivated by Jacques Rancière’s politics of aesthetics and Malcolm Andrews and W.J.T. Mitchell’s landscape theory, I proceed with my investigation in the form of a two-part interrogation: one that places emphasis on theory followed by a practical, creative response to Larkin’s image by way of repeat photography of Dump 20 and its surrounds. To demonstrate the concept of interface, I ‘excavate’ the aesthetic experience of Dump 20 as both sensory apprehension and through Rancière’s lens of emancipated viewership. There is an aesthetic quality of the sublime that appears to pervade visual representations of mined landscapes. Described as industrial sublime, toxic sublime or even apocalyptic sublime, the attention-holding quality these images exercise, through a strategy of aesthetic appeal, contribute to a politics of visibility by subversively implicating the viewer as a member of the human race. Global citizenship overrides national identity in these landscape representations, disrupting a sense of belonging with one of complicit participation in the formation of mined landscapes through reliance on mineral extraction for manufacturing consumer goods. Not only do representations of mined landscapes demand a rethink about aesthetic appreciation of landscape imagery and the endemic political connotations implicated in an understanding of landscape. They actively seek to penetrate surface visibility of land by taking into account the very pathology of land as an on going narrative of human and environmental interaction and life continually in process.
