Abstract: The Computer Mapping Center of the Detroit District, U.S. Army Corps of Engineers (USACE), in cooperation with the State of Michigan Department of Natural Resources (MDNR), Land and Water Management Division, is developing a Geographic Information System (GIS) to contain physiographic, environmental, and economic information of the U.S. shoreline of the Great Lakes. Emphasis is being placed on incorporating information on shoreline characteristics, current land uses, property ownerships, and habitats to be used for display, analysis and modeling of erosion/recession processes, storm-surge flooding, and wetland changes. The GIS framework is developed to utilize both raster and vector data storage, analysis, modeling, and presentation techniques. Shoreline characteristics and scanned aerial photography for study areas are encoded in raster formats. Current land use characteristics, property census and demographic data, recession rate and erosion processes data, wetlands maps, digital elevation data, and other specialized products are stored in vector formats. Additional tabular data, stored in relational data bases, are also linked to GIS mapped features as attributes.
