The WisDOT Geodetic Survey Unit has developed a Wisconsin Continuously Operating Reference Stations (WISCORS) Network consisting of permanent GPS sites, which provide real-time correctors to mobile users. Mobile users properly equipped to take advantage of these correctors can survey in the field to the 2-cm accuracy level in real-time. The program is being partnered with state and local governments, federal agencies, and educational institutions.

Active Network (WISCORS)

 

• The WISCORS network base coordinates will be adjusted from NAD83 (CORS96) to NAD83 (2011) on Sunday, March 10th. Effective March 10th, the system will no longer provide corrections referenced to the previous coordinate system.

• Sixty-four (64) CORS sites in Wisconsin are operational. CORS stations have been recently added in Northern, Central and Southwestern Wisconsin (see map of current network)


• Eleven (11) new CORS in Western Wisconsin will be added to the network on Sunday, March 10th.


• Six CORS will remain to be built in 2013


• Routine server maintenance is scheduled to take place the 3rd Sunday of each month. Work along the borders to partner with neighboring states is planned to begin after the initial development work is complete in 2013.
