* Not all bands of this sensor are used in EOReader
** P(panchro) have only one panchromatic band, P/MS-N have 3 bands (BGR), and P/MS-X also have 3 bands in false color (GRNIR)
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)
