In This Tutorial, I will present how to download ASTER 12.5 M resolution dem free.
The Ministry of Economy, Trade, and Industry (METI) of Japan and the United States National Aeronautics and Space Administration (NASA) jointly announced the release of the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) Global Digital Elevation Model Version 3 (GDEM 003), and the ASTER Water Body Dataset (ASTWBD) on August 5, 2019.
The ASTER GDEM V3 maintains the GeoTIFF format and the same gridding and tile structure as V1 and V2, with 30-meter postings and 1 x 1 degree tiles.
ASF’s Radiometric Terrain Correction Project
The creation of radiometric terrain corrected (RTC) products was a project of the Alaska Satellite Facility to make SAR data accessible to a broader community of users. RTC removes the geometric and radiometric distortions inherent in synthetic aperture radar (SAR) and the corrected PALSAR data are provided in a GIS-compatible GeoTIFF format.

The release of ALOS PALSAR RTC products commenced in October 2014 and was completed a year later. Data used in the RTC project were Fine Beam (FBS, FBD) and Polarimetric (PLR) scenes over all global land areas except Antarctica, Greenland, Iceland, and northern Eurasia.
