The GIS developed here includes data for: land ownership, topography (slope and aspect), bedrock and surficial geology, soil types, presence and orientation of bedrock lineaments, locations of water wells, culture (cities, roads, emergency facilities, etc.), and city and county zoning regulations. By incorporating and correlating features of all of these, it was possible to identify areas within Summit County that can accommodate increases in permanent population and the surges that characterize the tourist industry in Colorado.
