The Shuttle Radar Topography Mission (SRTM) collected elevation data over 80% of earth's land area during an 11‐day Space Shuttle mission. With a horizontal resolution of 3 arc sec, SRTM represents the best quality, freely available digital elevation models (DEMs) worldwide. Since the SRTM elevation data are unedited, they contain occasional voids, or gaps, where the terrain lay in the radar beam's shadow or in areas of extremely low radar backscatter, such as sea, dams, lakes and virtually any… Expand

Assessment of ASTER GDEM performance by comparing with SRTM and ICESat/GLAS data in Central China
TLDR
The ASTER GDEM shows better performance in the flat areas than that in the mountainous areas, and the accuracy improves with the increasing stack number, but has many artifacts including inland water noises and straight lines related to the irregular stack number boundaries. Expand
