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.

The only difference with the other bands is that the cloud bands are provided in uint8 and have a nodata equal to 255.

  • 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). If clouds are provided in probabilities, their presence is determined according to Landsat definition (proba> 67%)

  • CIRRUS: Cirrus presence (1) or absence (0). If clouds are provided in probabilities, their presence is determined according to Landsat definition (proba> 67%)

  • SHADOWS: Shadows presence (1) or absence (0). If clouds are provided in probabilities, their presence is determined according to Landsat definition (proba> 67%)

  • ALL_CLOUDS: Cloud OR Cirrus OR Shadows presence (1) or absence ( 0). Do not take into account missing bands (i.e. for Landsat MSS sensors, ALL_CLOUDS == CLOUDS)

DEM bands

Optical satellites can all load DEM, SLOPE and HILLSHADE bands. The SLOPE and HILLSHADE bands are computed with the gdaldem tool.

Use the environment variable EOREADER_DEM_PATH to position your worldwide DEM. You can use both a local path e.g. /mnt/dataserver/dems/srtm_30_v4/index.vrt or \\dataserver\DEMS\srtm_30_v4\index.vrt or a URL pointing to a web resources hosted on a S3 compatible storage e.g. https://s3.storage.com/dem-bucket/srtm_cog.tif (not available on Windows for now).

Default SNAP resolution

You can override default SNAP resolution (in meters) when orthorecifying SAR and S3 bands by setting the following environment variables:

  • EOREADER_S3_DEFAULT_RES (500m for SLSTR and 300m for OLCI data by default)
