Aster global digital elevation model aster gdem easy to use topographic information of the global terrain the ministry of economy trade and industry of japan meti and the national aeronautics and space administration nasa are collaborating on a project to develop aster global digital elevation model aster gdem a dem data which is acquired by a satellite borne sensor aster to cover all the land on earth.

Aster global digital elevation map gdem v2

. As with the previous version version 3 was developed with a 30 meter spatial resolution and is available in. The development of the aster gdem data products is a collaborative effort between national aeronautics and space administration nasa and japan s ministry of economy trade and industry meti. Fundamentals of gis how to use traveltime search api to create isochrones. It has an along track stereoscopic capability using its near infrared spectral band and its.

Aster global digital elevation map announcement. The aster global digital elevation model gdem version 3 astgtm provides a global digital elevation model dem of land areas on earth at a spatial resolution of 1 arc second approximately 30 meter horizontal posting at the equator. The improved gdem v2 adds 260 000 additional stereo pairs improving coverage and reducing the occurrence of artifacts. Version 3 of the advanced spaceborne thermal emission and reflection radiometer global digital elevation model is now available from nasa s land processes distributed active archive center the aster gdem covers land surfaces between 83 n and 83 s and was produced through automated processing of 2 3 million scenes from the aster archive.

The aster gdem v2 maintains the geotiff format and the same gridding and tile structure as v1 with 30 meter postings and 1 x 1 degree tiles. 2 3 million scenes from the aster archive were processed to create the latest version of the aster global digital elevation model gdem. Developed from aster scenes dating from march 1 2000 to november 30 2013 the geographic coverage extends from 83 north to 83 south. The aster gdem data products are created by the sensor.

On june 29 2009 nasa and the ministry of economy trade and industry meti of japan released a global digital elevation model gdem to users worldwide at no charge as a contribution to the global earth observing system of systems geoss. The aster advanced spaceborne thermal emission and reflection radiometer instrument was built by meti and launched onboard nasa s terra spacecraft in december 1999. 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. Aster gdem global digital elevation model has been produced as a joint activity of the ministry of economy trade and industry meti of japan and the united states national aeronautics and space administration nasa.

This version 1 aster gdem gdem1 was compiled from over 1 2 million scenebased dems covering land surfaces between 83 n and 83 s latitudes. The refined production algorithm provides improved spatial resolution increased horizontal and vertical accuracy and superior water body coverage and detection.
