The E6 PLSS database, part of a multi-year effort, was created as a sub-project of the greater Version 10 Statewide Parcel Map Database Project (V10 Project), a collaboration between the Wisconsin Land Information Program, the State Cartographer’s Office, and county data contributors. More information about the Statewide Parcel Map Initiative can be found here. The E6 database contains a collection of all uniquely identifiable local-level PLSS data available in digital format, and aggregates that data into a standardized schema and format. It also includes section, quarter-section, and quarter-quarter-section level polygons. The construction of the PLSS corner locations contained within the database relies on the local level coordinate information. This unique aspect of the database, allows for an accurate representation of the on-the-ground location of the PLSS corners.
