Dear users and developers,
SNAP 9 has introduced a very promising feature that corrects the effect of ionosphere, mostly due to the total electron content change between SAR pairs. The technique is based on state-of-the-art procedures, using the splitband technique.
This is a HUGE feature that is super important in slow-moving areas, where this component is the same order of magnitude as the displacement we want to measure. For that, I’d like to thank the SNAP development team.
This being said, I see an increasing number of users that are asking me (or via the official forum) how to use it. As I’m currently speaking, this functionality is not present in tutorials. If I’m wrong, please redirect me to the document.
It would be really nice to have a structured protocol on how to use / parametrize the module, and where to use it in a standard Interferometric protocol. If that’s possible, can a tutorial on subject be added to a “wish list” somehow? Or at least an answer here in Common Workflow Language
