Hi Margherita,

There are a lot of very different possible workflows with S-1, depending on what you are aiming at…

For terrestrial mapping applications, feel free to take inspiration from here (finishing off a report on the project right now):

https://github.com/NINAnor/sentinel4nature/blob/master/Tree%20canopy%20cover/preprocessing/sentinel_1_pp.sh

However, first parts of the pre-processing has to be done in SNAP / gpt as the relevant radar tools are to my knowledge not available in GRASS…

Cheers

Stefan

Hello Stefan
Thanks for sharing.
I will be using S-1 to estimate soil moisture, including time variations, so your script will certainly have some inspiration.

Best regards,
Micha

Stefan,

I overlooked to mention that my aim is to explore the capabilities for detecting areas of deforestation. Thanks for sharing your workflow! It will surely be useful for me.

Kind regards,

Forgot to upload the graph.xml file, where the SNAP processing chain is described…

Will upload the latest version with variables (instead of hardcoded file path) to github.

The attached file should open in SNAP GUI, however…

Cheers
