During its 11-day mission, the Space Shuttle Endeavour, carrying SRTM, orbited the Earth 16 times. As part of this mission, it captured Earth’s topography at 1 arc-second (30 meters) for over 80% of the Earth’s surface.. Using synthetic aperture radar and interferometry, SRTM has collected …

WebMar 27, 2024 · The new model has been generated at three separate resolutions (horizontal post spacings) of 30 arc-seconds (about 1 kilometer), 15 arc-seconds (about 500 meters), and 7.5 arc-seconds (about 250 meters). Released at the beginning of 2024, FABDEM offers a bare earth simulation of the earth's surface at 30 arc-second resolution. Adapted from GLO-30, the data removes all forests and buildings. The data is free to download non-commercially and through the developer's website at a cost commercially. An alternative free global DEM is called GTOPO30 (30 arcsecond resolution, c. 1 ibor abor 違い
