Tri-Decadal Global Landsat Orthorectified ETM+ Pan Mosaic V1Entry ID: MOSAICETM
Abstract: These data products consist of pan-sharpened versions of the ETM+ scenes above. The pan-sharpening process involved a resolution merging process, which allows the fusion of the higher-resolution panchromatic band (8) with selected lower-resolution multispectral bands (7,4,2) to create a higher-resolution ("pan-sharpened") color image.
The Tri-Decadal Global Landsat Orthorectified data ... collection consists of a global set of high-quality, relatively cloud-free orthorectified MSS, TM and ETM+ imagery from Landsats 1-5 and 7. This dataset was selected and generated through NASA's Commercial Remote Sensing Program, as part of a cooperative effort between NASA and the commercial remote sensing community to provide users with access to quality-screened, high-resolution satellite images with global coverage over the Earth's land masses. The data collection was compiled via NASA contract with Earth Satellite Corporation (Rockville, MD) in association with NASA's Scientific Data Purchase program.
The Tri-Decadal Global Landsat Orthorectified data collection consists of approximately 7,500 MSS (Landsat 1-5) images, 7,461 TM (Landsat 4-5) images and approximately 8,500 ETM+ (Landsat 7) images, which were selected to provide three full sets of global coverage over an approximate 25-year interval (circa 1975, circa 1990 and circa 2000). All selected images were either cloud-free or contained minimal cloud cover. In addition, only images with a high quality ranking in regards to the possible presence of errors such as missing scans or saturated bands were selected.
