GeoData@Wisconsin is developed and maintained by UW-Madison Geography Department's Robinson Map Library and State Cartographer's Office. The portal combines an intuitive, map-based search interface along with traditional text-based metadata search tools for rapid GIS data discovery for use in teaching, learning, research or for general interest.

Data Holdings:
The data layers available for download through GeoData@Wisconsin represent Wisconsin municipal, county, regional planning commission and state agency geospatial data within the Robinson Map Library's geospatial archive. Mainly, these data include: tax parcels & assessment data, streets, land use, address points, municipalities, zoning, hydrography and building footprints. Wisconsin state agency holdings include data from the Wisconsin Department of Natural Resources; the Department of Agriculture, Trade and Consumer Protection; the Legislative Technology Services Bureau and others. The acquired data collections continue to grow as new themes of interest are added each year.

Use Constraints:
Some data downloads in GeoData@Wisconsin are available for educational use only, and users must login with their UW System school credentials. All state agency data is available for public download. The Access column indicates which layers are restricted or publicly available.

Metadata records are authored by Robinson Map Library staff and include relevant information provided by the original data producers (if applicable.) Map Library staff may assist with questions pertaining to the metadata, however, questions about the data sets themselves are best directed to the originator listed as the primary contact in the metadata.

Additional Data Available from the Map Library:
For data that is older than 2012, as well as other layer options for Wisconsin counties and municipalities, please visit the Robinson Map Library website for a complete inventory of geospatial data holdings, Wisconsin GIS data. Use the online request form to request this data directly from the Map Library: Data Request Form.

GeoData@Wisconsin is part of The Open Geoportal. The Open Geoportal is a consortium comprised of contributions of several universities and organizations to help facilitate the discovery and acquisition of geospatial data across many organizations and platforms. Built on open source technology, the Open Geoportal provides organizations the opportunity to share thousands of geospatial data layers, maps, metadata and development resources through a single common interface.
