Optical bands

The following bands are available in EOReader, but may not be available for all sensors.

Satellite bands

These bands are mainly based on Sentinel-2 bands with some additions:

  • CA: Coastal Aerosol
  • BLUE
  • GREEN
  • RED
  • VRE_1: Vegetation Red Edge 1
  • VRE_2: Vegetation Red Edge 2
  • VRE_3: Vegetation Red Edge 3
  • NIR: Near Infrared
  • NARROW_NIR: Narrow Near Infrared (band 8A for Sentinel-2)
  • WP: Water vapour
  • SWIR_CIRRUS
  • SWIR_1
  • SWIR_2
  • PAN: Panchromatic
  • TIR_1: Thermal Infrared 1
  • TIR_2: Thermal Infrared 2

See here for more information.

Cloud bands

Maximum 5 cloud bands are available, according to the files provided in the data. All the bands are rasterized and orthorectified if needed (for Sentinel-2 or 3 data for example), ready to be stacked.

  • RAW_CLOUDS: Raw Cloud file as provided (the only changes are the orthorectification and rasterization). Can provide other flags, or cloud probability.
  • CLOUDS: Cloud presence (1) or absence (0).
  • CIRRUS: Cirrus presence (1) or absence (0).
  • SHADOWS: Shadows presence (1) or absence (0).
  • ALL_CLOUDS: Cloud OR Cirrus OR Shadows presence (1) or absence (0). Do not take into account missing bands ( ie. for Landsat MSS sensors, ALL_CLOUDS == CLOUDS)

See here for more information.

DEM bands

These bands need a valid worldwide DEM path positioned thanks to the environment variable EOREADER_SAR_DEFAULT_RES

  • DEM
  • SLOPE
  • HILLSHADE

See here for more information.
