What we do

The Geodetic Unit works with engineers and land surveyors, both public and private, to:

Establish and maintain horizontal and vertical control for all MnDOT projects statewide. This work is performed to the standards and specifications of the National Geodetic Survey office for inclusion in the National Geodetic Spatial Reference System.
Develop and provide technical support for new technology in precise surveying and mapping applications, and provide instruction and hands-on training in the use of precise leveling instruments and proper procedures for the use and adjustment of geodetic coordinates.
Develop a statewide geodetic database and provide technical support for Geographic Information Systems and Land Information Systems.
