ALOS PALSAR data is processed to L1.1 using the JAXA processor, then radiometrically terrain-corrected using GAMMA commercial software. Products are offered in FBS, FBD, and PLR beam modes. Low-resolution (30 m) products are produced in all land areas, with some exceptions.

DEMs
Complete DEM coverage is required for processing to proceed. GAMMA software handles differences in pixel-as-point vs pixel-as-area, and produces a uniform output.
