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...

Updating the 1:50.000 topographic maps using ASTER and SRTM DEM: the case of Athens, Greece [6366-6]

The 1:50.000 topographic maps present a nominal horizontal accuracy of 20 meters and a nominal vertical accuracy of 10 meters with 90% confidence. The data were in most cases extracted with photogrammetric techniques from aerial stereo-photographs during the 80’s. The usual update rate for these maps ranges from ten to twenty years. The Advanced Spaceborn Thermal Emission and Reflection Radiome...

Assessment of Srtm, Ace2 and Aster-gdem Using Rtk-gps

To date, the majority of digital elevation models (DEMs) are generated using photogrammetric methods. Recent remote sensing techniques, such as radar interferometry (InSAR), have also been used to generate high quality DEMs over a great area. Spaceborne high resolution DEMs with almost global coverage, such as SRTM, ACE2 and ASTER-GDEM, were made available to the public in the last few years. T...

On the suitability of the SRTM DEM and ASTER GDEM for the compilation of topographic parameters in glacier inventories

Topographic parameters in glacier inventories are a requirement to analyze glacier characteristics and are of vital importance for several subsequent applications. To obtain the topographic information a digital elevation model (DEM) is required; however, in many regions of the world no national or local DEM of sufficient quality is available. With the SRTM DEM and the ASTER Global Digital Elev...
