Terrain correction moves pixels to more accurately represent features such as mountains.
This data recipe is for users who wish to terrain-correct CEOS-formatted data granules for platforms including ERS-1, ERS-2, JERS-1, RADARSAT-1, and Level 1.5 ALOS PALSAR. Radiometric correction steps using the Ulander algorithm are included. However, the correction is not as accurate as that found in commercial SAR processing products. (Radiometric correction alters pixel values to more accurately reveal surface features such as vegetation and soil moisture.) You can terrain-correct CEOS-format data by following the recipe on this page. Note: most ALOS PALSAR data in the ASF archive have been radiometrically terrain-corrected.
