Moreover, specifying locations of features relative to geodetic control makes it possible to assess the positional accuracy of these features. Interest and activity regarding geodetic control have dramatically increased, corresponding to the need for accurate maps and surveys for development, infrastructure and geographic and land information systems.
To this end, the Survey Division of the Engineering Department maintains the Geodetic Control Network (GCN) within the City of Garland, Texas. Contact the Survey Group, at 972-205-2170 or for any questions concerning the network, email City Surveyor.
