Tri-Decadal Global Landsat Orthorectified ETM+ Pan Scene V1
Entry ID: ETMPAN


Summary
Abstract: Abstract: The 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 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 two full
sets of global coverage over an approximate 10-year interval (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. Purpose:
To provide users with access to quality-screened, high-resolution satellite images
with global coverage over the Earth's land masses. Supplemental_Information: The
average acquisition date for the Landsat Orthorectified ETM+ data is 2000 (+/- 1
year). All scenes were acquired between 1999 and 2001. These data have been
orthorectified for coregistration with the earlier (circa 1990) Landsat TM coverage.
