The City Surveyors are responsible for establishing a system of elevation control points throughout the City, known as Bench Circuits. Additionally, in concert with the Pima County Surveyors, the City maintains an elaborate network of geodetic control points that were established by GPS. Both geodetic and elevation data are also available via MapTucson under the Survey Research sub-layer. The City Surveyor also maintains 2 continuously operating reference stations (CORS) (COT1, COT2), which downloads station data for post processing. Information regarding this station should be directed to the City Surveyor at (520) 791-5100.
