- 6378c31c-75e6-47dc-b59b-87221ec46ea3 definition "GeoSAR (Geographic Synthetic Aperture Radar) is an airborne radar system that will generate high-resolution, three-dimensional maps to explore and study California. GeoSAR is being developed by a consortium consisting of the California Department of Conservation, Calgis Inc., and NASA's Jet Propulsion Laboratory, with funding provided the the Defense Advanced Research Projects Agency (DARPA). The project will develop a dual-frequency airborne radar system that will be able to collect 249 square kilometers (94 square miles) of data a minute. A special feature of GeoSAR will be its ability to acquire three-dimensional images of the Earth's surface through a technique call interferometry. Because GeoSAR uses radar, the system will be able to operate both day and night, under almost any weather condition. GeoSAR will be the first instrument that will be able to map both above, through, and below the vegetation canopy providing important information such a data about landslides that are overgrown with vegetation. The GeoSAR radar system is a dual frequency design using both P- and X-band wavelengths. The longer P-band wavelength will penetrate deeper into the canopy and, coupled with computer modeling, map beneath the vegetation canopy. When combined with other remote sensing data such as Landsat multi-spectral information, it will be possible to not only determine land cover type such as tree species, but also tree height and perhaps even width, such as crown diameter. Maps created with the GeoSAR data will be used to assess potential goelogic/seismic hazards, such as landslides, classify land cover, map farmlands and urbanization, and manage forest harvests. This system will become operational in early 2000. For more information see: 'http://southport.jpl.nasa.gov/html/projects/geosar.html'" @default.
