Version 1 Statewide Parcel Map Project Update

“V1 Parcels”

The Version 1 Statewide Parcel Map Database project is a collaborative effort between the SCO, the Department of Administration (DOA), and county level data contributors to create Wisconsin’s first publicly available statewide parcel layer. Known as “V1,” this project is the initial phase in achieving a searchable online parcel map, adhering to the requirements of Wisconsin’s Act 20, by 2017. These statutory requirements include parcel geometries, tax assessment data, zoning information, address data, and acreage.

Project update

With the project’s primary call for data occurring on October 23, 2014, we have to date received data from 69 counties and anticipate participation from all 72 counties within the next month.  During the data submission phase, the V1 team was at work developing a data model for the final deliverable and submitted its first interim deliverable to the DOA on December 31, 2014. This deliverable included five counties, and was focused on demonstrating aggregation tools and a preliminary attribute schema.

Where is the data now? 

Over the past two months, as county-level GIS and tax roll data has been rolling in, the V1 team has been busy documenting the nature of the data being submitted. During this data ingest phase, we are gaining knowledge of the data, detecting where gaps exist, and identifying characteristics to model in the deliverable’s schema so as to best preserve local-level data.

On the horizon

  • A second call for data, charted for mid-February, will target municipalities or other jurisdictions not included in county-level submission. Some counties will be reapproached to request specific missing data elements as well.
  • In the coming month, the V1 team will be refining the data model and tools as well as staging the data for aggregation.
  • Project staff Codie See and David Vogel will give a talk on the project on February 19, 2015, at the WLIA Annual Conference in Green Bay.
  • A second interim deliverable will be provided to the DOA on March 31, 2015.
  • The final deliverable will be provided to the DOA on June 30, 2015.

Thanks for participating! 

The State Cartographer’s Office and the Department of Administration are pleased with the positive response from data contributors and would like to thank all of the counties who have submitted their data to the V1 project!
