Instead of Terrain Correction or Ellipsoid Correction (which cannot be applied on Geocoded Products) just use Radar > Geometric > SAR Mosaic and add your layer as the only input. The result gets geocoded somehow.
This however only works if your image has no terrain induced distortions.
you can try if ASF MapRady supports ALOS-2 already.
I used it sometimes to geocode ALOS PALSAR Level 1.5 images. However I think that the routines for ALOS-2 are different and I think remembering that it crashed when I tried it once.
I’d say that depends on your application. If there is much foreshortening due to mountainous topography I coudn’t use it for geological mapping. But maybe for water body detection in the valleys it would be sufficient. A comparison with other spatial data (S2, basemap, OSM vectors…) should give a hint about the quality.
I did the trick SAR Mosaic on ALOS 2 L 1.5 and it worked well for the georeference. But I need to do the terrain correction since my study area is in Tapajos and we have some topography in the south and close to the river. How you managed to do the terrain correction? Did you do this is another software?
you can do this in ASF MapReady
This open source software correctly handles Level 1.5 products and performs great with calibrating, terrain correcting (both geometrically and radiometrically) and geocoding your image.
I installed ASF MapReady. I have backscatering images (sigma 0 hh, hv, vh, hh in db) after filter. I am trying to import those images to ASF MapReady, but it is not importing. I also tryed the original images ALOS 2, but the software says that is unable to import it (see the images bellow) . Does it work with ALOS 2? Maybe I did some mistake…
I did the sequence bellow and got the error . Many thanks in advance for your support.
