Acquiring information about a natural feature or phenomenon, such as the Earth's surface, without actually being in contact with it. USGS remote sensing is usually carried out with airborne or spaceborne sensors or cameras.
Describes the use of satellite-borne Interferometric Synthetic Aperture Radar (InSAR) to precisely measure, monitor, and assess small changes in land surface elevation resulting from human-induced or naturally occuring land subsidence.
We combine long-term records from aerial photographs, detailed mapping using survey-grade GPS, and ground-based lidar with meteorological monitoring. Sand dune migration rates are currently about 35 meters per year.
