NGS Survey Control Map

The NGS Survey Control Map provides a map of the US which allows you to find and display geodetic survey control points stored in the database of the National Geodetic Survey and access the geodetic control data sheets associated with the points. Data sheets are in ASCII format and show precise latitude and longitude, orthometric heights, and gravity data for individual survey control points.
