Geodetic Control Point Data

Geodetic control refers to permanent reference markers placed in the ground and precisely marked, located and documented. These markers provide accurate reference points to support the production of consistent and compatible data collection for surveying and mapping projects. Wisconsin has tens of thousands of survey control monuments placed by numerous agencies over many decades, so the avenues for finding control point information are varied.
