More information

MnDOT maintains a Geodetic Database for the registration of local surveying and mapping activities. This database contains information on permanent geodetic control marks and continuously operating reference stations located in Minnesota or just outside its boundaries. These provide precise horizontal and vertical control positions in the local area.

Information about the location of an object based on its geodetic control marks locates that object in a worldwide geographic information system. Marks have an object's unique identification and establishment year stamped on a monument disk made of brass or aluminum at 89mm (3 ½ inch) in diameter. These monuments consist of material (concrete or metal) that is meant to stay in place for 50 to 100 years or more, and have little or no movement due to frost action or activity near the monument.
