#esa_snap — Public Fediverse posts

ESA SNAP got updated.
Now #Sentinel2C data is supported, the Sen2Coral plugin is available and BandGroups have been added to the PinManager. Also, some issues have been fixed. See the changelog:

#earthobservation #esa_snap

With SNAP 11, released just yesterday, the configuration of ESA's snappy changed. It is not possible to configure it during the installation process anymore. You now need to install the esa-snappy plugin first, afterwards you can run the configuration script.

SNAP-Tutorials #10 - Rayleigh Correction Tutorial
This tutorial, by Ana B. Ruescas and Dagmar Müller, does not only show you how to do a Rayleigh correction at the example of #Sentinel-2, but also gives you scientific background information. The correction is not only applicable to Sentinel-2 MSI data, but also to Sentinel-3 #OLCI and #Envisat #MERIS data.

SNAP Tutorials #7 - Flood mapping using the Sentinel-1 imagery and the ESA SNAP S1 Toolbox
At the example of a flood in Germany in 2021 Luigi Selmi shows how a flood event can be mapped. Sentinel-1 data is used. The lesson not only provides information on the workflow but also on how SAR data can be interpreted and the structure of a Sentinel-1 product.

SNAP Tutorials #6 - Bulk Processing with GPT
This tutorial, by Marco Peters (yes me 🙂), gives an introduction on bulk processing with the command line on Windows and Unix systems. The provided scripts try to stay very generic to serve multiple processing requirements.

SNAP Tutorials #5 - SNAP Command Line Tutorial
SNAP not only provides a graphical user interface but can also be used from the command line. Luis Veci, one of the developers of SNAP, explains in this tutorial how the command line can be used for data processing. The command line tool gpt and the creation complex of processing graphs are explained.

#tutorial #esa_snap #snappy #eo #remotesensing

I'm starting a series of posts of tutorials for ESA SNAP for beginners and for advanced users. Some are already a few years old, but still can be used with the current SNAP version. Please forgive me, that I have not watched and stepped through all these videos. But at least I went through them quickly. If you have any problems with the tutorials, let me know. The first one will be published tomorrow. So. stay tuned
