USGS Landsat 7 Surface Reflectance Tier 1 (LANDSAT/LE07/C01/T1_SR)

This dataset is the atmospherically
corrected surface reflectance from the Landsat 7 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
and include a cloud, shadow, water and snow mask produced using
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.
