Analsysis of Aster Gdem Elevation Models
Digital elevation models (DEM) are of fundamental importance for remote sensing. With a DEM the three-dimensional positioning, requiring a stereo model can be reduced to a two-dimensional solution just based on a single image. With the free of charge availability of the SRTM-height models, covering the land area from 56° southern up to 60.25° northern latitude a nearly world wide coverage is gi...

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 کاملElimination of the Outliers from Aster Gdem Data
Digital Elevation Models (DEM) provided by stereo matching techniques often contain unwanted outliers due to the mismatched points. Detected outliers are candidate for wrong data that may otherwise adversely lead to model misspecification, biased parameter estimation and incorrect results (Maimon and Rokach, 2005). Therefore detection of outlying observations and elimination of them from the da...
متن کاملAssessment 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...
