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...

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...

Nowadays, like many other fields, DEM is widely used in the field of hydraulic engineering. In our studies, we compared DEMs (SRTM, ASTER GDEM v2, and ALOS PALSAR) for area recommended construction Shurbulak water reservoir. Contours were developed all with contours a topographic map. The SRTM PALSAR closely match on map than ASTER. Vertical differences between SRTM, GDEM2, products computed ro...

DEM can be generated from a wide range of sources including land surveys, Photogrammetry, and Remote sensing satellites. SRTM 30m by The Shuttle Radar Topography Mission (SRTM), the Global Digital Elevation Model Advanced Spaceborne Thermal Emission Reflectance Radiometer (ASTER GDEM) global surface model called ALOS Worldview 3D 30 meter (AW3D30) Land Observing Satellite (ALOS) are satellite-b...

Upon completion of the SRTM project, assessing the accuracy of the SRTM elevation data and its correlation to conventional photogrammetric methods has been a focus for many research projects. To date, elevation models derived from OrbView-3 and IKONOS have not had a significant number of comparisons to SRTM data. This study attempts to quantify the relative differences between elevation data co...
