Alos 2 Geo-reference

gusortiz has stumpled upon a solution for level 1.5 ALOS data.

I cannot promise that it works for any of you but it’s worth a try:

ALOS-1 L1.5 Terrain Correction

Dear users, The ALOS-1 L1.5 images are already map projected (GRD), but are not terrain corrected (orthorectified). All the SNAP tools in “Terrain Correction” or “Elipsoid Correction” do not work with the L1.5 images and give as error: “Source product should not be map projected.” So, how may we orthorectify those images using SNAP? Best regards, Gustavo

ALOS-1 L1.5 Terrain Correction

I did a “trick” that solved it: used the SAR-Mosaic with only 01 image. The output is corrected.
