Hello all,
I’ve read the posts regarding how to use specific DEMs in Sen2cor.
In my case, unfortunately, there is no SRTM for my Region of Interest - the arctic.
I changed all the parameters and even created a polygon with the same dimension of a SRTM tile that included my DEM but didn’t work.
Anyone had the same problem?
Thank you very much
Dear @SofiaB,
In order to process Sentinel-2 images over the arctic region using a digital elevation model, you can rely now on the Copernicus DEM that has been released to the community through the Copernicus programme:
https://spacedata.copernicus.eu/fr/collections/copernicus-digital-elevation-model
You can use SenCor version 2.11 to process these images and refer to point 2 of the Sen2Cor FAQ:
2) Configure DEM
Since the release of Sen2Cor 2.2, Digital Elevation Maps can be used for two purposes:
Improvement of the scene classification and improvement of the terrain correction.
The usage of a DEM is not set by default. It has to be set manually in the L2A_GIPP.xml
Sen2Cor 2.11 now fully support the Copernicus DEM.
Please refer to the Section 2.2.8 of the Sen2Cor Software User Manual
Cheers,
