Global Image Dataset at 15m Resolution
MDA Geospatial Services U.S. today announced the release of EarthSat NaturalVue, the only global 15-meter resolution natural color image dataset in existence today. EarthSat NaturalVue 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, EarthSat NaturalVue 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.
"EarthSat NaturalVue is 30 times more detailed than the next highest resolution global natural color dataset," said Roger Mitchell, MDA Geospatial Services U.S. Vice President. "We believe it will become the cartographic standard at these scales."
EarthSat NaturalVue 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, EarthSat NaturalVue 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.
