South Africa, 9 February 2007 – ComputaMaps, South Africa-based provider of geospatial data solutions, has announced the release of BrightEarth, a natural colour image mosaic covering 95% of the Earth’s land surface at a resolution of 14.25m.
The source for BrightEarth is the orthorectified Landsat 7 imagery acquired between 1999 and 2002 for NASA’s GeoCover programme. Using a proprietary algorithm, ComputaMaps has transformed the original false-color GeoCover imagery mosaics into a single color-balanced global mosaic with bright, vivid natural color that retains the high contrast detail of the original pan-sharpened source imagery.
BrightEarth imagery has less than 10% cloud cover for 90% of source scenes, and has an absolute horizontal accuracy of ±50m RMSE with many areas under 25m. BrightEarth is an ideal global imagery base for Internet map portals, location-based services, mobile content and navigation, 3D visualization and flight simulation, security and relief agency logistics, or any application where a seamless, highly detailed, geographically accurate, and realistic view of the world is required.
BrightEarth is available in UTM or Geographic projection, WGS84 datum, by individual country or continent, or as a single global coverage in a variety of compressed and uncompressed formats.
