Welcome to the
LTSB GeoData Collector

Formerly known as WISE-Decade

The LTSB GeoData Collector is a specialized web platform for Wisconsin counties and local governments to upload and document their official GIS boundaries.

Geographic Layers

Municipal boundaries, wards, county supervisory boundaries, parcels, and school districts.

Easy Upload

Upload data layers quickly, easily, and all in one place on the Upload Page.

Standardized Data

Data is standardized, merged, and publically distributed as authoritative statewide layers.

Publically Consumable

Used by Wisconsin Election Commission, DOA, DPI, US Census Bureau, and more.

BAS Collection

The BAS Data Collection application compares U.S. Census Bureau geography with local municipal data. Using the legal boundary changes submitted to the DOA Municipal Data System, annexation documents can be selected and associated to the specific boundary change for the U.S. Census Bureau to reference. The collection of municipal wards is mandated by state law 5.15(4)(br)1.
