Hey everyone, so far I’ve only used SNAP for dealing with Sentinel imagery (creating some basic DEMs/REMs, etc). However, for my thesis, I want to check if I can use high-resolution SAR imagery to detect small landscape changes (specifically to detect trench development, which could be useful for local conflict prediction).
For simple SAR imagery, certain groups such as Umbra or Capella have started providing high enough resolution to see trenches. However, I’d like to try to perform coherent change detection on interferograms to detect them better (single SAR images don’t provide a big benefit compared to spectral imagery, but InSAR would be massive).
The issue: As far as I’m aware Umbra imagery (which seems like the best option for creating high resolution interferograms) is not compatible with SNAP.
The question: A: By now, are there any other SAR providers that provide high resolution SLC imagery that can be used to create interferograms. or B: Is there alternative software (open source or not) that can be used to create interferograms based on the data that is available.
You can use TerraSAR-x imagery which I think is the highest resolution sensor handled by SNAP.
COSMO-SkyMed and Radarsat-2 are also an option but the resolution is lower.
NASA’s ISCE is an open source alternative.
Other commercial software you could use include GAMMA, Sarscape & Sarproz (if it’s for your thesis you can get a free trial version for Sarproz i think)
