The GDEM covers the planet from 83 degrees North to 83 degrees South (surpassing SRTM 's coverage of 56 °S to 60 °N), becoming the first earth mapping system that provides comprehensive coverage of the polar regions. It was created by compiling 1.3 million VNIR images taken by ASTER using single-pass stereoscopic correlation techniques, with terrain elevation measurements taken globally at 30-meter (98 ft) intervals.

These improvements include increased horizontal and vertical accuracy, better horizontal resolution, reduced presence of artifacts, and more realistic values over water bodies. However, one reviewer still regards the Aster version 2 dataset, although showing 'a considerable improvement in the effective level of detail', to still be regarded as 'experimental or research grade' due to presence of artefacts. A 2014 study showed that over rugged mountainous terrain

It has been collecting data since February 2000. ASTER provides high-resolution images of Earth in 14 different bands of
330-630: The electromagnetic spectrum , ranging from visible to thermal infrared light. The resolution of images ranges between 15 and 90 meters. ASTER data is used to create detailed maps of surface temperature of land, emissivity , reflectance , and elevation. In April 2008, the SWIR detectors of ASTER began malfunctioning and were publicly declared non-operational by NASA in January 2009. All SWIR data collected after 1 April 2008 has been marked as unusable. The ASTER Global Digital Elevation Model (GDEM)

396-515: The ASTER version 2 data set can be a more accurate representation of the ground than the SRTM elevation model. ASTER v3 was released on August 5, 2019. The improved GDEM V3 adds additional stereo-pairs, improving coverage and reducing the occurrence of artifacts. The refined production algorithm provides improved spatial resolution, increased horizontal and vertical accuracy. The ASTER GDEM V3 maintains
418-478: The high nominal resolution, however, some reviewers have commented that the true resolution is considerably lower, and not as good as that of SRTM data, and serious artifacts are present. Some of these limitations have been confirmed by METI and NASA, who point out that the version 1 of the GDEM product is "research grade". During October 2011, version 2 of Global Digital Elevation Model was publicly released. This
