ASTER Global DEM Validation

Accuracy of Dem Genaration from Terra-aster Stereo Data

In this work we studied the accuracy of DEMs generated from ASTER stereoscopic images by automated stereo-matching techniques with two different softwares (OrthoBase PRO and OrthoEngine). We compare several DEMs generated for a test area of 23 km x 28 km situated in the province of Granada (south Spain). This is an area was selected because its variable and complex topography with elevations ra...

Evaluation of ASTER GDEM2 in Comparison with GDEM1, SRTM DEM and Topographic-Map-Derived DEM Using Inundation Area Analysis and RTK-dGPS Data

This study evaluates the quality of the Advanced Spaceborne Thermal Emission Radiometer-Global Digital Elevation Model version 2 (ASTER GDEM2) in comparison with the previous version (GDEM1) as well as the Shuttle Radar Topographic Mission (SRTM) DEM and topographic-map-derived DEM (Topo-DEM) using inundation area analysis for the projected location of the Karian dam, Indonesia. In addition, th...

EVALUATION OF SAMPLES OF THE ASTER GLOBAL DEM USING STAR-3i AIRBORNE INTERFEROMETRIC SAR DATA

A recent Announcement of Collaborative Opportunity (AOCO) [1], offers an invitation to interested parties to participate in an exercise to validate the new ASTER Global DEM (GDEM). At the time of this abstract submission, the ASTER GDEM has not yet been released but is expected to be available for validation purposes in early 2009 and for general use later in 2009. The validation program is co-...

The accuracy of a DEM derived from ASTER data using differential GPS measurements

ASTER is a high-spatial resolution, multispectral imaging system flying aboard TERRA, a satellite launched in December 1999 as part of NASA’s Earth Observing System (EOS). An ASTER scene covering 61.5 km x 63 km contains data from 14 spectral bands. An ASTER Digital Elevation Model (DEM) is generated using bands 3N (nadir) and 3B (backward) level 1A images acquired by the Visible Near Infra-red...
