GIS Data

​​​DATCP programs create, use and maintain a wide variety of data in GIS format to support their business needs. The most frequently requested DATCP GIS data sets are available by contacting datcpgis@wisconsin.gov.

  • DATCP Coordinate Reference System: To facilitate data integration within the agency and with other state agencies, DATCP has adopted the Wisconsin Transverse Mercator coordinate system of 1983 based on the 1991 adjustment to the North American Datum of 1983 – WTM83, NAD83 (1991) for short– and provides its GIS data in this system. DATCP staff is not available for coordinate system conversions as part of GIS data downloads or requests.

  • DATCP Data Format: DATCP provides vector data (point, line or polygon data) in ArcGIS file geodatabase (version 10.2 +) format. DATCP staff may be available to convert agency GIS data to ArcGIS shapefile format upon request.
