Looking deeper into the ceos2 code it seems to me that the "recipe" for
decoding ALOS-PALSAR products do not match at all specifications I can
find at

http://www.eorc.jaxa.jp/ALOS/en/doc/fdata/PALSAR_L10_J_ENa.zip

Does that recipe refers to another format specification document?


Also, regarding the ceos2 driver in general, I didn't find an obvious
way to support CEOS products with multiple image files (like multi
polarization PALSAR or ALOS PRISM).

Did I missed something?
