New Vertical Geodesy
Vertical geodesy is undergoing a revolution because of two factors. First, new precise three-dimensional position measurement techniques used over very long distances and based on extraterrestrial reference systems provide a new class and precision of geometric data previously unavailable for geophysical investigations. Second, physical models in tectonic theory for large earthquakes predict cr...
متن کاملGEODESY The Concept
The following second definition represents a more up-to-date description of geodesy given by the Committee on Geodesy of the U. S. National Academy of Sciences in 1978. • Establishment and maintenance of national and global three dimensional geodetic networks • Measurement and analyses of geodynamic phenomena (earth rotation, earth tides, crustal movements, etc.) • Determination of the earth's ...
