Level of Effort



GeoData@Wisconsin enables discovery and access of Wisconsin geospatial data, imagery, and scanned maps. The Coastal Collection provides access to over 1,200 geospatial datasets with relevance to the Lake Superior and Lake Michigan coasts of Wisconsin.


  • Access current and historical county data layers for counties across Wisconsin, including roads, land use, building footprints, and other information
  • Access the WisconsinView archive of remotely sensed raster data and imagery for Wisconsin, including NAIP aerial images and county-based LiDAR
  • Discover coastal datasets used throughout the Coastal Atlas

Guidance & Resources

GeoDat@Wisconsin combines a map-based spatial search with traditional keyword searching and faceted browsing options to locate and download geospatial data. Many datasets in the geoportal are housed in the UW-Madison Robinson Map Library’s geospatial data archive, while others are hosted by the original data producers.
