Administering consultant contracts in conjunction with statewide geodetic control issues. The US National Geodetic Survey has produced DS World, a free program that can query their database for the positions of geodetic survey marker stations based on either state/county, distance from a fixed coordinate, or Project ID. By viewing the Mark List you can view and sort the attributes of the markers. Please install, Position the point of interest (POI) in the center of the view. These reference marks made it easier for later visitors to "recover" (or re-find) the primary ("station") mark. These markers were used to identify important topographical features, and to serve as control points in manual surveying to measure elevation; this particular marker (first pic below) is a triangulation marker that was used for that . This utility contains two different maps that show the distribution of sites that participate in the CORS Network: Use tools on the left side of the Google map to zoom in and out and move/pan as well as go to Street View.
