Information for Land Surveyors


This section provides information on surveying in Wisconsin primarily as related to mapping. From here you have access to applications for statewide geodetic control stations and Public Land Survey System corners (PLSS), and CORS data for Wisconsin (including links to the WISCRS). Users can also obtain information pertaining to the Wisconsin Height Modernization Program (HMP), which improves the density of geodetic control stations listed in the National Spatial Reference System (NSRS) with accurate orthometric heights (elevations) throughout the state. In addition, our resource links provide quick access to a variety of survey-related topics.

Expansion of Moore Road in Barnes

Moore Road in Barnes was expanded and we didn't want to lose any section corner monuments due to the construction. This meant going out, finding the reference pipe, using a metal detector to locate the corner, and then using GPS to mark the location so we can locate it again in the future.
