Frederick, USA, 11 June 2007: EarthData International, Inc., part of the Fugro Group, has been awarded a $5.9 million contract to complete aerial mapping over parts of South America for the United State’s National Geospatial-Intelligence Agency (NGA). Data acquisition for the 70,755-square-kilometer project will commence this month.
As with previous NGA contracts in the region, EarthData will use GeoSAR radar mapping system to produce high-resolution image and terrain maps in support of land and information management activities.
“GeoSAR is perfectly suited for mapping equatorial regions like these,” stated EarthData President Anne Hale Miglarese. Mounted on a jet aircraft and capturing X- and P-band radar data simultaneously, GeoSAR penetrates the characteristic dense vegetation and near-constant cloud cover that renders conventional aerial mapping techniques cost-prohibitive or impossible.
GeoSAR is an airborne radar mapping system that collects dual-band interferometric synthetic aperture radar (IFSAR) data in a single pass, day or night, and in almost any weather condition. EarthData GeoSAR customers receive a suite of five standard products—a top-surface image and elevation model, a corresponding image and terrain model beneath the trees, and a series of laser profiles for every flight line.
