what's changed

in snap?


The Image Processing software we used within the book was the Sentinel Application Platform (SNAP), which is available to download via the European Space Agency (ESA) science toolbox exploitation platform (step) http://step.esa.int/main/download/. SNAP is open source software, and so it’s freely available. It’s also regularly updated, especially the modules within in, which means that the version of SNAP we used within the book will not be the same version you download.

The version of SNAP used within the first (2016) edition was version 2.0 beta 0.6, whereas the second (2023) edition uses version 9.0.0.

It’s possible to download older versions of SNAP, but you will be using a newer version as module updates will have occured. So, we’d recommend using the newest version as it will contain any bug and updates fixes.

Help on SNAP is available via the step forum http://forum.step.esa.int/

If there is anything in the book that you cannot find in the latest version of SNAP, or anything that does not appear to work as we indicated, please log-in and let us know in the forum.
