Development of a GIS for the U.S. Great Lakes Shorelineby Roger L. Gauthier, US Army Engineer District, United States,
Abstract: The Computer Mapping Center of the Detroit District, U.S. Army Corps of Engineers (USACE) is developing a Geographic Information System (GIS) to contain physiographic, demographic, and economic information of the U.S. shoreline of the Great Lakes. The GIS framework is developed to utilize both raster (gridded) systems approaches and vector (linear and polygonic) mapping and analytic capabilities. Shoreline characteristics are encoded in a raster base and current cover/use characteristics are encoded in vector formats. Future directions include the porting of demographic and land value data bases into the vector domain and linking project design files to GIS real-world depictions for modeling and analysis.
