I have a number of ALOS-2 products (level 1.1, geotiff) that I would like to process. I understand CEOS format would be better but this is not an option unfortunately.
I run into an issue at the first step and cannot open the products in SNAP. Either by using ‘open product’, or ‘Import’>‘SAR sensors’> ‘ALOS-2 GeoTIFF’, I get the same error ‘there is already an image reader’. (error log below).
I have managed to open it as a generic GeoTIFF, but I then cannot perform any calibration or correction as it is not a SAR image.
Any help or guidance would be much appreciated!
