These two images are part of the Grand Canyon and are processed from the same PALSAR data. The image on the left is uncorrected. The image on the right is terrain-corrected. In the uncorrected image, the sides of the canyon appear to be stretched on one side and compressed on the other side. Click to enlarge. ASF DAAC 2014; Includes Material © JAXA/METI 2008.

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. High-resolution (12.5 m) products are produced in areas with sufficient DEM support.

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.
