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.
