ASTER (Advanced Spaceborne Thermal Emission and Reflection Radiometer) is a global DEM that has been generated at a resolution of 1" (approximately 30m at the equator). ASTER is a cooperative effort between NASA and Japan's Ministry of Economy Trade and Industry (METI), with the collaboration of scientific and industry organizations in both countries. Due to the nature of the data and processing a number of researchers have noted the presence of striping effects within the DEM.
