CaSIL GeoFinder
GeoFinder is a tool that helps find and retrieve geographic and environmental data from the California Resources Agency, its consituent departments, and other partner organizations. GeoFinder lets users drill down through a map of California using predefined geographies like zip code, watershed, bioregion, county, urban area or by place name. Once an area of interest is identified, the user can easily locate and retrieve digital orthophoto quads and scanned USGS map sheets for the area. A user can also ask for a list of rare species and natural communities inventoried by Fish and Game.s Natural Diversity Data Base. GeoFinder also lets users easily crosswalk between these geographies.
