Mapping & Survey Data

The Commission’s Interactive Mapping Application provides data essential to the planning process and a separate app provides access to U.S. Public Land Survey System information.

Interactive Mapping Application

Regional mapping activities in Southeastern Wisconsin have involved planning agencies at both the regional and local level. The Commission has collected and prepared resource and planning-related mapping since 1963. Over the years, the Commission has acquired and developed a regional geographic information system of digital mapping that includes land use, environmental corridors, and other spatial data essential to the planning process.

At the local level, every county and many city, village, and town governments in Southeastern Wisconsin have developed digital mapping capabilities as part of their planning activities. These counties and communities maintain a variety of maps, including topographic, real property boundary line (parcel), and planning-related mapping, for use in their administrative and planning functions.
