From the point cloud produced the exported section profiles can be used to monitor deformations or displacements mainly in tunnels but also on other structures or landslide and. Accurate models of storm surge and pollution highway planning effective resource management and adequate disaster preparedness all require accurate elevations.

Geodetic experiments have been performed in the past with the solar eclipse star occultation and moon-position camera methods but for various reasons the experiments did not produce useful geodetic results.

Coast and Geodetic Survey which evolved into the National Geodetic Survey NGS in 1807. After the United States of America USA introduced a global positioning system GPS in 1980 satellite positioning methods became easy efficient precise and accurate getting rid of the limitation posed by terrestrial-based classical geodetic survey methods.
