USGS Landsat 5 Surface Reflectance Tier 2 (LANDSAT/LT05/C01/T2_SR)
This dataset is the atmospherically
corrected surface reflectance from the Landsat 5 ETM sensor.
These images contain 4 visible and near-infrared (VNIR) bands and 2 short-wave
infrared (SWIR) bands processed to orthorectified surface reflectance,
and one thermal infrared (TIR) band processed to orthorectified brightness
temperature. The VNIR and SWIR bands have a resolution of 30m / pixel.
The TIR band, while originally collected with a resolution of 120m / pixel
(60m / pixel for Landsat 7) has been resampled using cubic convolution to 30m.
These data have been atmospherically corrected using
LEDAPS,
and include a cloud, shadow, water and snow mask produced using
CFMASK,
as well as a per-pixel saturation mask.
Strips of collected data are packaged into overlapping “scenes” covering approximately
170km x 183km using a standardized reference grid.
