Continuously Operating Reference Stations (CORS) Data

Surveyors, GIS users, engineers, scientists, and the public at large that collect GPS data can use CORS data to improve the precision of their positions. CORS enhanced post-processed coordinates approach a few centimeters relative to the National Spatial Reference System, both horizontally and vertically.

Statewide

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.

National

The National Geodetic Survey (NGS), an office of NOAA’s National Ocean Service, manages a network of Continuously Operating Reference Stations (CORS) that provide Global Navigation Satellite System (GNSS) data consisting of carrier phase and code range measurements in support of three dimensional positioning, meteorology, space weather, and geophysical applications throughout the United States, its territories, and a few foreign countries.
