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...
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 کاملCorrecting Dem Extracted from Aster Stereo Images by Combining Cartographic Dem
The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on-board the NASA's Terra spacecraft provides along-track digital stereo image data at 15m resolution with a base-height ratio 0.6. Automated stereocorrelation procedure was implemented using the ENVI 4.1 software to derive DEMs with 15m×15m in 43 km long and 50 km wide area using the ASTER stereo images. The cloud areas...
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...
متن کاملDem Evaluation Generated from Hrs Spot5 Data
The purpose of this project is to test High Resolution Stereoscopic (HRS) data of SPOT5. This project is done in the framework of the “HRS study Team” international test, supported by ISPRS-CNES. The Digital Elevation Model (DEM) was derived from the HRS data and was evaluated by using a 3D reference data set. The study site for HRS data is located in Manosque, France. It is a countryside lands...
