July 14, 2004, Rockville, MD – Earth Satellite Corporation (EarthSat) today announced the release of NaturalVue 2000, the only global 15-meter resolution natural color image dataset in existence today. NaturalVue 2000 is based entirely on Landsat 7 data acquired between 1999 and 2001. Only the very best scenes with minimum cloud cover were selected.
Except for the high polar latitudes, NaturalVue 2000 covers the entire land area of the Earth. It is positionally accurate to better than 50m RMSE. NaturalVue, more accurate than nearly all maps at 1:100,000 scale, is excellent for mapping and GIS datasets.
“NaturalVue 2000 is 30 times more detailed than the next highest resolution global natural color dataset,” said Roger Mitchell, EarthSat Vice President. “We believe it will become the cartographic standard at these scales.”
NaturalVue 2000 has a wide range of geospatial applications. For multi-scale solutions, it can be seamlessly merged with higher resolution data sets, such as SPOT, IKONOS and QuickBird. Fused with a digital elevation model, NaturalVue 2000 is used for flight and 3-D simulation, mission planning, natural resource inventory, and land cover studies.
The entire uncompressed global data set approaches 4.0 terabytes. Compressed versions of the product are also available. The entire NaturalVue dataset can be viewed at:

EarthSat is part of the MDA Geographic Information Products group, specializing in the production of information solutions for natural resource, defense readiness, and global change problems. EarthSat has developed and patented several image information extraction techniques, including a massive block triangulation technique, called MOSPOLY, and a localized contrast enhancement program, both of which were utilized in creating this unique data set. Under NASA contract, EarthSat has mapped the entire world with Landsat data for three time periods: circa 1975 with MSS data; circa 1990 with Landsat TM data; and circa 2000 with Landsat ETM+ data. These three data sets are known, collectively, as the GeoCover-Ortho Products. EarthSat used proprietary image processing techniques to create NaturalVue 2000 from GeoCover-Ortho 2000 data.
