V4 statewide parcel web app and data download now available

The Wisconsin Department of Administration (DOA) and State Cartographer’s Office (SCO) are pleased to announce the release of the Version 4 Statewide Parcel Data within the Statewide Parcel Web Application and Statewide Parcel Data Distribution Page.

The Statewide Parcel Web App continues to provide the community with a web-based mapping interface for browsing the V3 (2017) and V4 (2018) statewide parcel layers. The application enables users to pan and zoom, search by parcel attribute information, locate themselves on the parcel map, and query parcels on screen.  Although no longer available in the application, the V1 (2015) and V2 (2016) parcel layers are still available for download.

The statewide parcel layer is available for download in its entirety as an Esri file geodatabase. Individual county downloads are available as shapefile or file geodatabase.

Database Characteristics

The V4 Project is part of a larger Statewide Digital Parcel Map Initiative, a multi-year, DOA initiative that resulted from Act 20, the state’s 2013-15 biennial budget. The V4 schema documentation includes detailed information about available attributes. The V4 change log highlights changes to the statewide parcel layer since it was first publicly released as “V1” on July 31st, 2015. Attributes contained in the V4 database are consistent with those contained within V1, V2 and V3. They include but are not limited to:

  • Assessed value of land
  • Assessed value of improvements
  • Total assessed value
  • Class of property, as specified in s. 70.32 (2)(a)
  • Estimated fair market value
  • Total property tax
  • Parcel owner names
  • Property and mailing address information maintained by the county
  • Acreage information maintained by the county
  • Parcel ID
  • School districts
  • Latitude/Longitude of parcel centroid
