GeoSAR is an airborne radar mapping system that produces 3D terrain data and imagery for generation of topographic maps and other derived products.
The system uses a technology known as interferometric synthetic aperture radar. Widely referred to as IFSAR, this technology is the radar equivalent of stereo vision in photogrammetry.
GeoSAR is the world’s only radar mapping system that simultaneously maps the ground beneath foliage (using P-band) and the surface features above the terrain using (X-band), in a single pass.
The system’s dual-band, dual-sided configuration rapidly acquires high resolution elevation data and radar imagery over regions previously considered inaccessible due to extreme weather and/or rugged terrain. GeoSAR is available worldwide exclusively from Fugro.
GeoSAR is the world’s only multi-band, single-pass airborne radar mapping system. Based on interferometric synthetic aperture radar technology, commonly referred to as IFSAR or InSAR, GeoSAR operates at very high altitudes and speeds to simultaneously map surface features (using X-band) and near bare-earth elevation (using P-band).
Developed in partnership with NASA’s Jet Propulsion Laboratory, Fugro commercialized the system in 2002 and has since mapped over 900,000 square kilometers using this one-of-a-kind system.
Our in-house radar engineers and scientists continue to improve the system’s capabilities and throughput while also expanding the range of applications that can be supported by GeoSAR data.
