Python client

Logging in

For participants interested in trying thing out, try logging into Terrascope openEO backend:

https://docs.terrascope.be/#/Developers/WebServices/OpenEO/OpenEO

Jupyter notebooks with the openEO Python client installed: https://notebooks.terrascope.be

This jupyter environment also has the notebook samples in this git repository already available:

https://github.com/VITObelgium/notebook-samples

Otherwise, git can be used to check out the notebooks, or simply download the 'ipynb' file.

Use 'edugain and social accounts' login to avoid having to register at Terrascope, you may still be required to fill in a form.
