For each MSS, TM, ETM+, and OLI image downloaded, several outputs are created. From these single image outputs, annual cloud-free image composites are derived by infilling where clouds are present and taking the mean pixel value from overlapping near-date images.

MSS image data

  • 4-band DN raster stack
  • 4-band radiance raster stack
  • 4-band atmospherically corrected surface reflectance
  • 3-band TM-calibrated tasseled cap raster stack
  • 1-band TM-calibrated tasseled cap angle raster
  • 1-band cloud and shadow mask raster

TM/ETM+ image data

  • 6-band atmospherically corrected surface reflectance (LEDAPS) raster stack
  • 3-band tasseled cap raster stack
  • 1-band tasseled cap angle raster
  • 1-band cloud and shadow mask raster

OLI image data

  • 7-band atmospherically corrected surface reflectance (L8SR) raster stack
  • 3-band ETM+ -calibrated tasseled cap raster stack
  • 1-band ETM+ -calibrated tasseled cap angle raster
  • 1-band cloud and shadow mask raster

Composite image data

  • 1-band annual cloud-free tasseled cap brightness raster
  • 1-band annual cloud-free tasseled cap greenness raster
