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.
Study to identify grasslands that may be suitable for cellulosic feedstock production. Producing ethanol from non-cropland areas such as grassland will minimize the effects of biofuel developments on global food supplies.
Examples of the use of Satellite Interferometric Synthetic Aperture Radar to measure and map changes on the Earth's surface as an aid to understanding how ground-water pumping, hydrocarbon production, or other human activities cause land subsidence.
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.
Georeferenced high-resolution mapping of bathymetry of the West Florida Shelf, Gulf of Mexico of areas suspected to be critical benthic habitats for fisheries. Includes links to images, data, metadata, and TIFF image files.
Enables locating and ordering aerial photography produced under the National Aerial Photography Program (NAPP)from the EROS data center with links to product description, prices, search & order, custom enlargements and certification.
