Automatically detect subswaths and bursts according to AOI #6

Closed loreabad6 closed 2 years ago

loreabad6 commented 2 years ago

When computing the interferograms, the subswath and burst need to be manually set. It would be good to automatically detect these to cover only our area of interest and therefore get a subset of the whole scene processed.

Currently, we check on SNAP where the intersection is.

Two possible options:

S-1 TOPS SPLIT Analyser (STSA)
- Already a package which seems to create shapefiles for the bursts and swaths. We could in theory intersect this with our AOI and know which bursts and subswath is needed.
snap2stamps
- Based on graphs so probably not super

I implemented this by using S-1 TOPS SPLIT Analyser (STSA) tool. Initially the output was always written to a .json but I now use an internal function of the package to get it as a GeoDataFrame. For now it is working as expected 🥳
