SCO Project: Version 1 Statewide Parcel Database Project


The Statewide Digital Parcel Map Initiative is a multi-year, multi-facet, DOA initiative resulting from Act 20, the state‚Äôs 2013-15 biennial budget bill. The Act directed the DOA to develop a parcel map implementation plan and established a requirement for counties to post certain parcel information online by 2017, including property tax assessment data, zoning information, address data, and acreage. The initiative consists of two key development cycles for the statewide parcel map, V1 and V2.

Version 1 Statewide Parcel Database Project ("V1")

Project Leads: State Cartographer's Office, Wisconsin Department of Administration Division of Intergovernmental Relations

Timeframe: July 1, 2014 - Sept. 30, 2015

Overview: The Version 1 Statewide Parcel Database Project is the first of two development cycles within the Statewide Digital Parcel Map Initiative. This project successfully created a statewide GIS parcel database aggregated from existing county and municipal parcel datasets, and was made available to the public on July 31, 2015.  The publicly available layer includes the parcel attributes required by statute and is available for viewing through a web application and through statewide file geodatabase download

In addition to the publicly available statewide parcel layer, the V1 project has focused on the following items, which are addressed in the V1 interim report:

  • Making recommendations for a searchable format for parcel attributes.
  • Identifying benchmarks to assess completeness of digital parcel data.
  • Providing quantitative assessments of each county parcel dataset in terms of these benchmarks.
  • Describing tools used to standardize county and municipal datasets.
  • Making recommendations for a county data export standard for integration into a statewide parcel database.
  • Analyzing longer-term benchmarks going beyond the immediate statutory needs for posting parcel information online.
