Classification and cloud mask

Hello sentinelhub-team,

I want to detect artificial coverages on agricultural land. Is it possible to do an supervised classification on sentinelhub? You have some help for automatic multiple Scene classification?

The L2A scene classification for example mix some white artificial coverages with clouds. Where can I find the SCL-script?

Where can I find s2cloudless-results from CLP (cloud probabilities) and CLM (cloud masks) on sentinel hub? Are they different to L2A scene classification or they have the same decision tree?

Thanks

Hi @bgumwelt,

it is not possible to run supervised classification directly in Sentinel Hub.
You might however find this blog post series relevant, where we demonstrate, start-to-end, on how to do supervised classification using eo-learn and Sentinel Hub, with a Jupyter Notebook sample with all the steps:


You should be able to modify this for your use-case pretty easily.

An example of the script for SCL is here:

You can find CLM and CLP cloud masks directly along the Sentinel-2 bands, see:

More info here:
https://docs.sentinel-hub.com/api/latest/#/API/data_access?id=cloud-masks-and-cloud-probabilities
The masks are not the same as L2A scene classification, as those are done using Sen2Cor algorithm and CLM/CLP use s2cloudless algorithm.
