Abstract. The project "Risk Map Germany" at the Center for Disaster Management and Risk Reduction Technology (CEDIM) aims at visualizing hazards, vulnerabilities and risks associated with natural and man made hazards. CEDIM as an interdisciplinary project unified various expertise like earthquake, storm and flood disaster research. Our aim was to visualize the manifold data exploration in thematic maps. The implemented Web-GIS solution "CEDIM Risk Explorer" represents the map visualizations of the different risk research. This Web-GIS integrates results from interdisciplinary work as maps of hazard, vulnerability and risk in one application and offers therefore new cognitions to the user by enabling visual comparisons. The present paper starts with a project introduction and a literature review of distributed GIS environments. Further the methods of map realization and visualization in the selected technical solution is worked out. Finally, the conclusions give the perspectives for future developments to the "CEDIM Risk Explorer".

Abstract:

Trichonida lake has an area of 96,17Km2 and is situated at Etoloakarnania prefecture. In this study a data base has been developed, on geological, geomorphological and environmental data, concerning the wider zone around Trichonida lake. Different thematic maps have been created, using as input variables, the GIS database fields and the statistical analysis output from the MathLab software. Using MathLab software, the primary data has been transformed into fuzzy data sets and for each drainage basin an erodibility value was calculated. The final thematic map, present the erodibility values of each drainage basin. Such geographical GIS databases may be used in local or regional level for the study of erodibility problems, the development of thematic maps and moreover to decision support systems.

Abstract:

This paper presents a methodology for assessing the degree of vulnerability of different lithology formations constituting the drainage basin of the gorge of Agia Eirini. The methodology is based on the processing of spatial aspects parameters of lithology, hydrography, geomorphology and the vegetation cover, which are related with the weathering impact on formations either directly or indirectly. Initially a series of primary spatial data on geology, topography, the river network and the land use in the region, were used to produce thematic maps. These maps include the geological map, the digital terrain model (DTM), the map of the land use, and hydrographic maps of density and frequency. By processing the data according to their role in enhancing the vulnerability of formations, the data were determined and the following thematic maps: “Map of geological formations susceptible to weathering”, “Map of hydrographic texture”, “Map of morphological inclinations” and “land use map protecting against the loss of disintegrated material were produced. By appropriate combination of these secondary data, areas of vulnerability of formations were recorded which are shown on a final thematic map. This information is particularly valuable in the management planning and gives the opportunity to evaluate and predict the impact of various proposed projects or future scenarios. They can also be used to identify positions to take necessary measures to protect areas at high risk of loss of material.

Abstract:

The paper presents potential soil erosion risk of the upper Parsęta catchment (Drawskie Lake District, NW Poland). The model considers following conditions affecting the size of soil erosion: slope gradient, LS factor, lithology, land use and land cover. Thematic maps have been reclassified into a 4-degree division. Potential soil erosion risk map was prepared on the basis of thematic maps. Areas with small and moderate susceptibility to soil erosion occupy 71.5% of the catchment area. The 4th class of erosiveness is represented by the river valley slopes, steep slopes of kame and moraine hills, covering 28.5% of the upper Parsęta catchment.

Abstract:

This research is directed (main objective) towards differentiation, tracking and presentation of the functional sustainability trends of regional development in Bulgaria (NUTS BG3). The proposals are based on empirical and statistical information processed in the GIS environment for the period 2008-2016. The used research approaches are general geographic and cartographic: cybernetic approach; systematic and correlation analysis; choropleth mapping and proportional symbols. The subject of this analysis is Goal 1. of the Sustainable Development Agenda 2030, which states:“End poverty in all its forms everywhere“. The object of this research is Bulgaria (NUTS BG3). The obtained results was presented in three thematic maps, one table and one figure. Our main goals was: Presentation of the results from the considered aspect of the regional policy for sustainable development of the European Union in Bulgaria, based on the absolute values of the considered indicators (Thematic map 1 and 2); Determination of the trend of functional sustainability of regional development in Bulgaria as a means of mapping the impact of centrifugal and centripetal forces, creating and exacerbating the spatial imbalances - center / periphery in Bulgaria. (Thematic map 3) The obtained results show the decrease in the absolute values of people at risk of poverty or social exclusion and the increase of GDP per capita. The differentiated trend of functional sustainability of regional development in Bulgaria (Thematic Map 3) was transformed and supplemented on the basis of established subjectivity in the interpretation of the impact of the phenomena under consideration (the rate of people at risk of poverty or social exclusion and GDP per capita) . As a result, it was structured a method for mapping the impact of centrifugal and centripetal forces, generating and deepening the spatial imbalances - center / periphery in Bulgaria (in particular).

Abstract:

Accurate assessment to disaster risk is one of the keys to reducing disaster losses. However, due to the fact that the disaster situation data series in county unit are always relatively short, available data are often not sufficient for disaster risk analysis. In this paper, a risk analysis method based on information diffusion theory was applied to create a new disaster risk analysis model (CURAM), and the risk of disaster can be evaluated on higher spatial resolution of county unit. Visual Basic and Map Objects were used to establish CURAM applying object oriented technique and component technique. CURAM provided risk evaluate function to natural disaster in county unit, and thematic map making and output, etc. The risk assessment results calculated by CURAM indicated that information diffusion technology was highly capable of extracting useful information and therefore improved system recognition accuracy.

Abstract:

The maps of altitude, geology, vegetation cover and land use were prepared and classified as the main criteria to locate soil and water conservation programs. Analytical Hierarchy Process (AHP) was used to determine the relative priorities of these criteria by pairwise comparison. All the thematic maps were then integrated using the overlay process in Geographical Information System (GIS) and the final map of soil erosion risk was produced. Results indicated that vegetation cover was given the highest weight (0.494). The geology was assigned the second highest weight (0.313), as the main cause of initiation of the erosion of erodible lands. Land-use change has a local influence on soil erosion, so it was assigned the third weight (0.151). Altitude is a low-impact variable for predicting the water and soil conservation areas.

Abstract:

<p><strong>Abstract.</strong> One of the main tasks that have been addressed within the project “Dynamic Mapping Methods Focused on Risk and Disaster Management in the Big Data Era” was how to deal with a scale-dependent modification of a thematic content. Thematic content on this type of maps is composed of point-based observations from different sources. Assembled maps are organized according to particular risk phenomena and previously mentioned point observations indicate status of the risk in selected theme. These indicators come from a variety of different sources, such as automatic sensors, volunteer observations, geographically localized patterns on the web and social networks etc. The user of the map has to first select a key indicator and subsequently a set of support indicators, to customize the map to his requirements. Naturally, when scaling down, graphical conflicts between map elements must be resolved. However, the cartographic generalization has to be done in such a way as to also highlight content and preserve the context of presented observations. In the context of the previous paragraph, it was clear that the most suitable cartographic generalization method for our purposes was an aggregation. Generally, the aggregation is a transformation of group map objects into smaller group of map objects (usually on just one target object). In our case we can identify following target objects of the aggregation:</p><ul><li>A multiple observation symbol resulting from aggregation of either several close symbols of the same kind, or several heterogenous symbols to highlight importance or dominance of one specific kind,</li><li>A rectangular array of symbols resulting from aggregation of conglomeration of heterogenous symbols,</li><li>An area that is the aggregation of a bounded array of objects of the same type, areal shape is derived from simplified convex hull of affected symbols, nevertheless, in some cases, the concave hull and best-fit ellipse were also tried,</li><li>An isopleth representation of value regularly distributed symbols of the same kind, where isopleths are derived from IDW interpolation either of the symbol value or by symbol density, border lines of zones are simplified and invisible.</li></ul><p> For the purpose of controlling the generalization process, it is necessary to set the conditions for generalization of the map objects. Such conditions - constraints are in this case relatively simple - symbol size is fixed, symbols cannot overlap, symbols are closer to their original location then other symbols (rectangular group of symbols is considered as one aggregated symbol). It is also necessary to choose which transformation mechanism belongs to which group of map objects. Given the small complexity of the situations and the need for rapid identification of the generalization operator, we have chosen rule-based control system. Rule set is extensible and stored in a database, its core is small due to a cover transformation of group of point symbols to one entity expressed by potentially four representations (or its combination). Because isolated objects are rarely present on the map, key role in the generalisation process plays a structure recognition. Process of the structure recognition is triggered by symbol collision. Identified symbol collisions are clustered by distance and clusters are solved together. For each type of symbol present within an individual cluster, cartometric measurement are made in the cluster’s vicinity. The resulting parameterization leads to the rule identification. Several possibilities how to prioritize rules, in case of ambiguity and impact of their setting on the generalization process are also further discussed.</p><p>Second, but not less important part of the article, is dedicated to the implementation of the cartographic generalisation process. Because the final goal is to build a web map, the implementation is based on web technologies. Core of the implementation is based on node.js server. All processing tools were defined as JavaScript functions. For geoprocessing purposes, open source library Turf was used, because this technology falls under MIT license. Measurements and rules were stored in open source LevelGraph database. This graph database has nowadays no particular advantage in the limited scope of cartographic generalisation process, but it seems to be promising for possible future and more complex projects. Another reason why beforementioned tools were selected is the possibility to transfer the whole generalization process to the client-side web browser. Input thematic data are the result of a query on web service which provide us evaluated anomalies and their cross references. For visualisation purposes were used open source interactive web maps library OpenLayers.</p>

Abstract:

This paper introduces the solution for Dalat city’s soil erosion mapping using the integration of GIS, Remote Sensing and the Universal Soil Loss Equation (USLE). Each of the USLE factors with associated attribute data are dicussed and the soil erosion parameters were selected and encoded in a GIS database to produce thematic layers. The result demonstrates the soil erosion map that indicates the potential annual soil loss located in each area of land. This map is used to confirm the severe level of soil erosion risk need immediate attention from soil conservation point of view.

Choropleth maps are a popular way of depicting spatial data. The map communication model, which theorizes that geographic information is transmitted from the cartographer to the map user via a map, suggests that cartographers are responsible for clearly conveying spatial data in a way all map users can understand. Map users, however, come from different places and may harbor certain regional biases. This thesis investigates whether map users tend to focus on data patterns within their home regions during the visual-search and decision-making processes when reading classed choropleth maps, thereby exhibiting an egocentric map behavior. Seventy-one subjects took a computer-based test asking them to identify various phenomena on a series of choropleth maps of the lower 48 states. The results show a weak positive effect of egocentric map behavior; subjects who lived in a particular state longer were slightly more likely to choose states nearby their home region.

Abstract:

Maps are increasingly being used in traditional and virtual media, and civic discourse on political, social, and environmental issues, among others, is more and more becoming influenced by them. The often-used expression of a “picture tells a 1000 words” has never been so apt in our progressively more visual world. Despite this increased role and importance of maps, map literacy, as a field of research, remains rather underdeveloped. This is especially so for thematic maps, the very type of map that is finding increasing currency in discourse. As part of this under-developed nature of map literacy, the quantitative skills used in map reading and interpretation have not been systematically investigated, and previous commentary on the subject has been limited to listings of relatively low-level skills. As modern technologies, such as GIS, enable the more sophisticated production of maps, their interpretation can come to depend on more advanced quantitative literacy. The quantitative literacy required for map interpretation can also be expected to vary significantly with the type of map, and while map literacy studies generally recognize the broad distinction of reference and thematic maps, they do not provide a more nuanced framework for investigating how quantitative literacy may vary both within these broad categories and for maps which overlap these categories. This dissertation represents a first attempt to address these issues, and at least provide conceptual frameworks for their investigation. For the first conceptual framework, the dissertation introduces a three-set Venn model to discuss the content and relationships of three “literacies”: map literacy, quantitative literacy, and background information. As part of this, the field of Quantitative Map Literacy (QMP) is introduced and defined as the knowledge (concepts, skills and facts) required to accurately read, use, interpret, and understand the quantitative information embedded in geographic backgrounds. It is conceptualized as the intersection of the Map Literacy and Quantitative Literacy “sets”. The dissertation also introduces the conceptual framework of a compositional triangle based on the ratio of reference to thematic map purpose and the level of generalization/distortion within maps. This framework allows for any type of map to be located within the triangle and then related to the type and level of quantitative literacy they demand. Finally, based on these two frameworks, the dissertation uses the pedagogical tool of “word problems” to explore the variability of map reading skills and knowledge, and does this for specific map examples.

The increasing concern with the environment and specially with the use of the water resources resulted in the increasing valorization of the drinking water as well of consumption. Innumerable are the activities that use this resource, one of them, the Car Wash Station (CWS), object of this research. In Brazil, about 32,700 CWS approximately consume 3.7 millions of cubical meters of water per month that transform it in wastewater. In this context, this work had, as general objective, the development of alternative technology for wastewater treatment aiming the recovery of the water from car wash station. For so much, the methodology had as base seven main aspects: 1) diagnosis of the current situation around the activity of CWS; 2) characterization of the crude wastewater generated by CWS; 3) mathematical modeling to identify the critical factors of project; 4) development of the prototype; 5) researches of patents to verify the innovation; 6) elaboration of the process for patent request and 7) specifications of the criteria for development of installation and operation manuals of the wastewater treatment system. In the case of Toledo/PR city, from the 47,155 registered self-driven vehicles (of the whichonly 27% pass for CWS), with a medium consumption of 2682,5 m3 water per month, it was verified a generation of 2.921,14 m3 wastewater per month with highly variable characteristic, having only 97% of the CWS some treatment system. The inefficiency of the conventional systems was verified and the analysis resulted in the proposition/development of two technologies (patent request number MU8701195-6 23/07/2007 and number MU8701196-4 23/07/2007) having, among their characteristics, the low cost,installation/operation/maintenance easiness, need of little space, efficiency and versatile in application form. In this way, this work should intended to contribute with the minimization of the environmental problem around the activity of CWS
A crescente preocupação com o meio ambiente e, em especial com o uso dos recursos hídricos resultou na valorização crescente da água potável como bem de consumo. Inúmeras são as atividades que utilizam este recurso, uma delas, os Postos de Lavagem de Veículos (PLV s), objeto da pesquisa. No Brasil, cerca de 32.700 postos de lavagem transformam aproximadamente 3,7 milhões de metros cúbicos de água/mês em efluente. Neste contexto, este trabalho teve como objetivo geral o desenvolvimento de tecnologia alternativa para tratamento de efluentes visando a reutilização da água de postos de lavagem de veículos. Para tanto, a metodologia teve como base sete aspectos principais: 1) Diagnóstico da situação atual em torno da atividade dos PLV s; 2) Caracterização do efluente bruto gerado pelos PLV s; 3) Modelagem matemática para identificar os fatores críticos de projeto; 4) Desenvolvimento do protótipo; 5) Pesquisa em banco de patentes para verificar a inovação; 6) Elaboração do processo para pedido de patente e 7) Especificações dos critérios para desenvolvimento de manuais de instalação e operação do sistema de tratamento de efluentes de PLV s. Para o caso da cidade de Toledo-PR constatou-se a existência de 47.155 veículos automotores cadastrados (dos quais apenas 27% passam pelos PLVs), com um consumo médio de 2682,5 m3 de água/mês, geração de 2.921,14 m3 de efluente/mês com característica altamente variável, tendo apenas 97% dos postos algum sistema de tratamento. Constatou-se a ineficiência dos sistemas convencionais cuja análise resultou na proposição/desenvolvimento de duas tecnologias (pedido de patente N° MU8701195-6 de 23.07.2007 e Nº MU8701196-4 de 23.07.2007) tendo entre suas características o baixo custo, facilidade de instalação/operação/manutenção, necessidade de pouco espaço físico, eficiente e versátil na sua forma de aplicação. Desta forma, este trabalho deve contribuir com a minimização da problemática ambiental em torno da atividade dos PLV s.

Abstract:

Access to the to the Internet and to a variety of interactive mapping tools has increased interest among middle school teachers to use interactive maps in conjunction with learning activities. There is very little research in the area of interactive mapping in educational situations, specifically with regards to layer maps that combine multiple thematic layers on a single map. This study evaluates the relationship between the number of layers present on a web-based map and middle-school students' accuracy and timeliness using the map to answer geographic questions. Additionally, this study examines the specific effect of a hill shade on student response time and accuracy when answering questions do not require any terrain information. Tests were conducted in five Portland, Oregon area middle school classrooms using Blackboard CE8 to present maps and collect responses. The results of this research indicate no significant relationship between the number of layers present on a web map and middle school students' accuracy or response times while using the map to answer questions. The presence of a hillshade layers does not significantly impact the students' response times or accuracy while answering questions while using the map either.

Abstract:

Background: The distribution of malaria in sub-Saharan Africa is determined largely by climatic influences on the development and survival of P. falciparum and its Anopheline vectors. This inter-relationship has been exploited in developing a limited number of predictive maps of malaria's distribution but these climate maps have limitations. Climate alone does not fully describe the complex dynamics of transmission and, in particular, human influences such as urbanization and the use of widespread anti-malarial interventions. The improved accuracy and validation of solely climatedriven maps relies on the availability of robust malariometric training data. To date, such data have been scarce. This study redresses several deficiencies of existing malaria maps for Africa through the collation of an extensive database of empirical P. falciparum prevalence data, the investigation of the relationship between prevalence and a widely-used climate-driven map, an assessment of the influence of urbanization on prevalence and finally, through the use of empirical training data to develop an improved malaria map for Kenya, Tanzania and Uganda. Methods: An extensive published and grey-literature search was conducted between 1996 and 2004 and identified 2003 P. falciparum prevalence surveys conducted among childhood populations across East Africa between 1927 and 2003. Stringent criteria were applied to select the best sample data; only randomly sampled community-based surveys, surveys with samples >=50 children, surveys conducted between 1980-2004 and children aged 0-14 years, and surveys which were spatially and temporally unique. The selected data were used to investigate the association between P. falciparum prevalence and a fuzzy logic climatic suitability (PCS) map of malaria transmission, the effect of urbanization on prevalence and to train Fourier-processed multi-temporal climate surrogate data derived from meteorological satellites in order to predict prevalence for un-sampled areas. Using discriminant analysis, the top ten climatic predictor variables that distinguished best between 4 categories of malaria prevalence (0-<5, 5-<25%, 25-<75% and >=75%) were selected and these used to develop a predictive transmission map.

Abstract:

Water contamination during urban flood events can have a negative impact on human health and the environment. Prior flood studies lack investigation into how GIS can map and analyze this at a large scale (cadastral) level. This thesis focused on how GIS can help map and analyze water contamination risk in urban areas using LiDAR elevation data, at a large-scale (cadastral) level, and symbology and flood classification intervals specifically selected for contamination risk. This was done by first completing a literature review about past research and studies of similar scope. Based on the findings, a method to map and analyze water contamination risk during sea-based flood scenarios was tested in the Näringen district of Gävle, Sweden. This study area was investigated and flood contamination risk maps were produced for two different flood scenarios which illustrated which properties are vulnerable to flooding and at what depth, what their contamination risk is, and if they are hydrologically connected to the ocean. The findings from this investigation are that this method of examining water contamination risk could be useful to planning officials who are in charge of policies relating to land-use. These findings could help guide landuse or hazardous material storage regulations or restrictions. To further research in this topic, it is recommended that similar studies are performed that use a more detailed land-use map which has information on what type and quantity of possible contaminants are stored on individual properties. Furthermore, flood modeling should be employed in place of the flood mapping which was conducted in this thesis.

Abstract:

The Geothecnical Thematic Mapping (GTM) was created inside of The Standard for Management of the Pipeline Structural Integrity (2002) and intends to predict geothecnical risk areas. These maps were made along five thousand kilometers of pipeways. The GTM has as its purpose of classify the pipeways and adjacent areas (400 meters) according to the area’s susceptibility to geological-geothecnic accidents. From this classification, inspection frequency was established in each portion of the strip. When this work is done, it will be possible to increase the knowledge of the geothecnical problems that exist throughout pipelines, allowing to ration out the utilization of the resources applied to field inspections. This work generated these products: - Features and geothecnical risk maps through photo interpretation techniques; - Potencial Geothecnical Risk Map acquired through GIS technology. These maps are incorporated to the GIS TRANSPETRO system, in such a way that allows its utilization by all the professionals involved. The GTM was obtained from the integration of two distinguished methodologies: indirect observation, through the utilization of photo interpretation techniques and the fusion of GIS processing. The photo interpretation of aerial susceptibility to geothecnical hazard, according to its intensity which is classified as high, medium and low susceptibility. The features and classifications of the risk identified during photointerpretation were digitalized and geo-referenced, making possible the check of the models adopted in the geoprocessing. All the generated data statistics were analyzed, in a way to point out areas where there was evidence of high risk of geothecnical occurrence. These analyses allowed the elaboration of a risk index. This index was calculated to portions of 5 Km of the pipeway, allowing its ranking in terms of high, medium and low susceptibility to geothecnic. In the end of the project, the company may have a good definition of all pipeways and of all the portions that represent a major probability of problems and where to allocate money for prevention.

Abstract:

During last year tourism and hospitality industry recorded significant losses due to the Covid-19 pandemics. One of the reasons is that indoor activities have been recognized as one of the main contributor to virus spread. Innovative technologies can play a key role in reducing indoor interaction between guests and staff, keeping social distancing, and providing a high level of cleaning standards. This research aimed to examine whether the implementation of innovative technologies may influence customers’ perception of health risk and whether their implementation in hotels may lead to greater travelers’ confidence in the COVID-19 era. An experimental study was conducted using online customer samples. The purposed questionnaire was developed based on preventive measures taken by leading hotels and hotel chains. The sample includes 180 examinees between 20 and 54 years of age. The results indicate that the implementation of innovative technologies in reducing contact and enhancing cleanliness have a significant impact on customers’ perceived health risk and restoring travelers’ confidence.

Abstract:

The paper addresses the problem of supporting research of the energy systems resilience. The resilience is concerned with the energy system ability to withstand large disturbances. To reach the goal of creating user-friendly software for decision making support in that field, a software platform is considered. It includes some original frameworks for retrieving, gathering, querying and analysing data, and building thematic maps to produce disturbance scenarios and evaluate consequences of their impact. The main advantage of the proposed platform is its applicability for all the stages of the energy system resilience research starting from risk mitigation assessment and ending with comparing alternative recovering or reconstruction strategies.

Abstract:

The Everglades National Park and Big Cypress National Preserve vegetation mapping project is part of the Comprehensive Everglades Restoration Plan (CERP). It is a cooperative effort between the South Florida Water Management District (SFWMD), the United States Army Corps of Engineers (USACE), and the National Park Service’s (NPS) Vegetation Mapping Inventory Program (VMI). The goal of this project is to produce a spatially and thematically accurate vegetation map of Everglades National Park and Big Cypress National Preserve prior to the completion of restoration efforts associated with CERP. This spatial product will serve as a record of baseline vegetation conditions for the purpose of: (1) documenting changes to the spatial extent, pattern, and proportion of plant communities within these two federally-managed units as they respond to hydrologic modifications resulting from the implementation of the CERP; and (2) providing vegetation and land-cover information to NPS park managers and scientists for use in park management, resource management, research, and monitoring. This mapping project covers an area of approximately 7,400 square kilometers (1.84 million acres [ac]) and consists of seven mapping regions: four regions in Everglades National Park, Regions 1–4, and three in Big Cypress National Preserve, Regions 5–7. The report focuses on the mapping effort associated with the Northwest Coastal Everglades (NWCE), Region 4 , in Everglades National Park. The NWCE encompasses a total area of 1,278 square kilometers (493.7 square miles [sq mi], or 315,955 ac) and is geographically located to the south of Big Cypress National Preserve, west of Shark River Slough (Region 1), and north of the Southwest Coastal Everglades (Region 3). Photo-interpretation was performed by superimposing a 50 × 50-meter (164 × 164-feet [ft] or 0.25 hectare [0.61 ac]) grid cell vector matrix over stereoscopic, 30 centimeters (11.8 inches) spatial resolution, color-infrared aerial imagery on a digital photogrammetric workstation. Photo-interpreters identified the dominant community in each cell by applying majority-rule algorithms, recognizing community-specific spectral signatures, and referencing an extensive ground-truth database. The dominant vegetation community within each grid cell was classified using a hierarchical classification system developed specifically for this project. Additionally, photo-interpreters categorized the absolute cover of cattail (Typha sp.) and any invasive species detected as either: Sparse (10–49%), Dominant (50–89%), or Monotypic (90–100%). A total of 178 thematic classes were used to map the NWCE. The most common vegetation classes are Mixed Mangrove Forest-Mixed and Transitional Bayhead Shrubland. These two communities accounted for about 10%, each, of the mapping area. Other notable classes include Short Sawgrass Marsh-Dense (8.1% of the map area), Mixed Graminoid Freshwater Marsh (4.7% of the map area), and Black Mangrove Forest (4.5% of the map area). The NWCE vegetation map has a thematic class accuracy of 88.4% with a lower 90th Percentile Confidence Interval of 84.5%.

Abstract:

The Sonoran Desert Network (SODN) conducted a vegetation mapping and characterization effort at the two districts of Saguaro National Park from 2010 to 2018. This project was completed under the National Park Service (NPS) Vegetation Mapping Inventory, which aims to complete baseline mapping and classification inventories at more than 270 NPS units. The vegetation map data were collected to provide park managers with a digital map product that meets national standards of spatial and thematic accuracy, while also placing the vegetation into a regional and national context. A total of 97 distinct vegetation communities were described: 83 exclusively at the Rincon Mountain District, 9 exclusively at the Tucson Mountain District, and 5 occurring in both districts. These communities ranged from low-elevation creosote (Larrea tridentata) shrub-lands spanning broad alluvial fans to mountaintop Douglas fir (Pseudotsuga menziesii) forests on the slopes of Rincon Peak. All 97 communities were described at the association level, each with detailed narratives including lists of species found in each association, their abundance, landscape features, and overall community structural characteristics. Only 15 of the 97 vegetation types were existing “accepted” types within the National Vegetation Classification (NVC). The others are newly described and specific to Saguaro National Park (and will be proposed for formal status within the NVC). This document is Volume II of three volumes comprising the Saguaro National Park Vegetation Mapping Inventory. This volume provides two-page summaries of the 97 associations identified and mapped during the project, and detailed in Volume I. Summaries are presented by district, starting with the Tucson Mountain District. These summaries are abridged versions of the full association descriptions found in Volume III.
