The ArcGIS for Local Government Basemaps are a set of ArcMap documents that can be used to author high-quality, essential basemaps for your local government. These basemaps are the foundation of many of the ArcGIS for Local Government applications and provide a consistent geographic context across local government departments and agencies. They include important reference information to orient map users and are typically combined with operational information managed by a department and/or agency within local government.
Each basemap is provided as an ArcMap document organized around the ArcGIS Online/Bing Maps/Google Maps tiling scheme. The data frame in each map document is reprojected to the Web Mercator Auxiliary Sphere Projection (WKID 102100 / 3857), but the source data is maintained in its local projection.
Local Government Basemaps requires specific technical experience and software.
