Hi
I have some question about change detection
first of all what is the best data format for change detection? slc or grd / IW or EW or WV or SM/ and what polarization?
second is there any tutorial or step by step processing guide for doing change detection?
Level 1.0 data cannot be opened in SNAP. It is basically Level 0 but with orbit information and some bit adjustments.
You need at least Level 1.1 (corresponds to a SLC image) or level 1.5 (MGD).
Exist one way for to georeference ALOS PALSAR images (1.5) with SNAP? I cannot make terrain correction with SNAP, which other way I should to implement?
Screenshot of my processing for make terrain correction of ALOS PALSAR images with SAR Mosaic in SNAP, I don’t believe that geometric distortion was corrected!!! I have doubt
Left: image with SAR mosaic, Right: Image without SAR mosaic
this was a misunderstanding. The work-around with the mosaic doesn’t address terrain-induced distortions. It just helps you projecting Level 1.5 data which is currently not supported by the RD Terrain Correction module or the reproject module.
I readed that geometric distortion are corrected with terrain correction, but this I cannot makes for ALOS PALSAR in SNAP, so, how could make this ??? Please help
Interesting, my understanding was that the 1.5 product was missing the slant-to-ground transformation coefficients which makes terrain correction impossible. We should look into this @lveci
