Municipal Boundaries Print
By Jim Lacy   

In Wisconsin, the Legislative Technology Services Bureau (LTSB) GIS Team works closely with local governments to maintain a statewide layer of municipal boundaries (cities, villages, and towns).  Counties are required by state law to submit updated municipal boundary data to LTSB. 

In addition, the U.S. Census Bureau collects governmental unit boundaries from all governments in the nation through its voluntary Boundary and Annexation Survey (BAS). LTSB is now required by statute to participate, on behalf of the state, in geographic boundary information programs when offered by the U.S. Bureau of the Census. The municipal boundaries that are collected every spring are used to submit data to the BAS program.
