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-...
متن کاملExternal Validation of the ASTER GDEM2, GMTED2010 and CGIAR-CSI- SRTM v4.1 Free Access Digital Elevation Models (DEMs) in Tunisia and Algeria
Digital Elevation Models (DEMs) including Advanced Spaceborne Thermal Emission and Reflection Radiometer-Global Digital Elevation Model (ASTER GDEM), Shuttle Radar Topography Mission (SRTM), and Global Multi-resolution Terrain Elevation Data 2010 (GMTED2010) are freely available for nearly the entire earth’s surface. DEMs that are usually subject to errors need to be evaluated using reference e...
متن کاملError Estimation of Aster Gdem for Regional Applications - Comparison to Aster Dem and Als Elevation Models
The last 20 years show an enormous resolution improvement of worldwide available Digital Elevation Models. At present, the ASTER Global Digital Elevation Model (GDEM) with a resolution of 30 m shows an evolution from the GTOPO 30 model (1000 m) of the year 1996 and the SRTM model (90 m) of the year 2000. However, little is known about the accuracy of the ASTER GDEM itself and for the official t...
متن کاملMapping from ASTER stereo image data: DEM validation and accuracy assessment
The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on-board the National Aeronautics and Space Administration’s (NASA’s) Terra spacecraft provides along-track digital stereo image data at 15-m resolution. As part of ASTER digital elevation model (DEM) accuracy evaluation efforts by the US/Japan ASTER Science Team, stereo image data for four study sites around the world h...
متن کاملEvaluation 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...
