Geospatial analysis of specific degradation in South Korea
… and aerial photos were used to better represent geospatial features affecting erosion and sedimentation. Long-term reservoir sedimentation measurements were available to determine the Sediment Delivery Ratio (SDR). An important finding from this analysis is that the percentage of the area covered …

A Geospatial Approach to Wildlife and Wilderness Management
The populations in the western United States have increased significantly over the last few decades resulting in increased development pressures on undeveloped and pristine lands. Population growth and increased human activities have also changed the overall ecosystems more rapidly and extensively …

Development of MIT geospatial data to CityGML workflows
… this thesis explores the process of translating geospatial data received from MIT into the CityGML data format, which will then be used to generate virtual environments for BlindAid. We discuss the main challenge of preserving both geometry and semantic information with respect to different data …
