Overview The Ohio Department of Transportation, Office of Aerial Engineering operates and maintains a network of 52 strategically located GPS Continuously Operating Reference Stations (CORS) in the State of Ohio, with a few stations located in Kentucky and West Virginia; these stations are providing data for post-processed and real-time positioning applications. All reference stations are network linked to a series of computers located at the State of Ohio Computing Center in Columbus, Ohio. Data Availability All 52 of the ODOT network CORS are currently part of the National Geodetic Survey (NGS) National CORS network. One second RINEX format GPS data is available for post processing through the NGS webpage. Real-time data is available for registered users via cell phones or wireless modems. The current RTK correction formats supported are: RTCM 2.3, RTCM 3.0 and CMR+.
