The science of accurately measuring and understanding the Earth's geometric shape, orientation in space, and gravity field. The NGS is the successor agency to the U.S. Coast and Geodetic Survey (USCGS). Thanks! [6] Each station mark in the database has a PID (Permanent IDentifier), a unique 6-character code that can be used to call up a datasheet describing that station. Survey markers were often placed as part of triangulation surveys, measurement efforts that moved systematically across states or regions, establishing the angles and distances between various points. the full Agency name will appear.
