ALOS-1 L1.5 Terrain Correction

[ABraun]

this is partly answered here:

Alos 2 Geo-reference

There are actually two kinds. 1.5 and 1.5G. The 1.5G is map projected and cannot be terrain corrected. It should be possible to reproject it. I’ll have to check if current error checking is to restrictive to allow it. All detected ALOS products from ASF that I’ve seen are 1.5G. I see some processed from Australia at level 1.5 which are just GRD but it’s missing SRGR coefficients so can’t be terrain corrected either.
