Optical data

Implemented optical satellites

The product resolution is the one given in Data Access Portfolio (2014-2022, section 6.2). The Data Access Portfolio Document presents the offer of the datasets and data access services that are made available to the Copernicus Users in response to their Earth Observation data requirements.

* Archived Landsat Collection-1 are not managed because of the tar.gz format, which is too slow to process. It is better to work on the extracted product. Landsat-9 Collection-1 products don’t exist.

** Maxar satellites: Worldview 2, 3, 4 and GeoEye-1, but other (such as WorldView-1, QuickBird…) with the same file format should be supported. The resolution can vary around the one given here.

Warning

Satellites products that cannot be used as archived have to be extracted before use.

The goal of EOReader is to implement every sensor that can be used in the Copernicus Emergency Management Service. The sensors that can be used during CEMS activations are (as of 09/2021):
cems_sensors

Optical bands

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

Warning

EOReader loads bands in UTM. VHR bands can be orthorectified but EOReader needs a DEM for that. Be sure to position the environment variable EOREADER_DEM_PATH to the DEM you want.

Satellite bands

Note

Optical bands are always loaded in reflectance. For Sentinel-3 SLSTR, radiances are converted to reflectance, expcept for brilliance temperature bands that are left as is.

These bands will be cleaned according to the user’s needs. By default, only the pixels outside the detectors footprints are set to nodata. Methods to clean optical bands are best described here.

Band names

These bands are mainly based on Sentinel-2 bands. The names are the ones from Sentinel-2, even if sometimes it can be confusing (especially for Coastal Aerosol and SWIR Cirrus bands).

Some additions to the Sentinel-2 bands have been made (YELLOW, PAN…):

Note

Note that bands that are not mapped can still be used (i.e. for Sentinel-3 OLCI and SLSTR). They will be called by their true name (i.e. F1 or Oa05). However, the mapped band will have to be called with their mapped name, i.e. BLUE rather than Oa04 for Sentinel-3 OLCI. But the bands that are not present in the alias file won’t be recognized.
