In a project area close to Istanbul the quality of WorldDEM, AW3D30, SRTM DSM and ASTER GDEM2 have been analyzed in relation to a reference aerial LiDAR DEM and to each other. The random and the syste...
The ALOS World 3D – 30 m (AW3D30), ASTER Global DEM Version 2 (GDEM2), and SRTM-30 m are Digital Elevation Models (DEMs) that have been made available to the general public free of charge....
A NEAR-GLOBAL BARE-EARTH DEM FROM SRTM     DEM  SRTM  Bare earth  Smoothing       2016/11/8
The near-global elevation product from NASA’s Shuttle Radar Topographic Mission (SRTM) has been widely used since its release in 2005 at 3 arcsecond resolution and the release of the 1 arcsecond versi...
One major problem engendered by poverty in less-developed countries is that of inability of such countries to carry out fresh medium-scale topographical mapping at regular time intervals usingexpensiv...
In order to determine the absolute accuracy of SRMT model on Polish area the research work has been performed on the basis of reference terrain profiles measured by GPS technique. The flat and hilly t...
Digital elevation models (DEM) are basic part of the information about an area. Knowledge about DEM quality is important for their use in management projects, engineering projects and geomorphologic s...
The method was then used to geo-reference old topographic maps of former Portuguese colonies, which were in local geodetic datums not well related to WGS-84. The consistency of planimetric datum shift...
This paper presents a methodology of image orientation and DEM extraction from ALOS-PRISM stereopairs without the use of GCPs. It uses the approximate geo-location information derived from the sensor ...
This paper evaluates the quality of SRTM3 data for alpine and plateau areas in Northwestern (NW) China against DEM data extracted from topographic maps. These SRTM data were obtained from both the ESR...
This work presents a methodology for the refinement of 90m digital elevation model (DEM) of Shuttle Radar Topographic Mission (SRTM) data. The SRTM DEM is publicly available through the Seamless Data ...
The paper presents results of a comparative study of the vegetation-caused elevation bias of the space shuttle topographic mission data product, both C- and X-band (SRTM.C/X). The SRTM.C/X bands data ...
COMPARISON OF SPOT,SRTM AND ASTER DEMs     DEM  SPOT  ASTER  SRTM  Accuracy       2015/9/17
Digital Elevation Models (DEMs) represent the terrain elevation in discrete form in three-dimensional space. This is the simplest form of 3D-terrain representation and the most common. The accuracy an...
HIGH RESOLUTION SRTM HEIGHT MODELS     SRTM  DEM  DSM  validation       2015/9/17
For the area of the United States the Shuttle Radar Topography Mission (SRTM) height models are available with 1 arcsec spacing instead of the 3 arcsec spacing outside the country. Only special users ...
The SRTM (Shuttle RADAR Topographic Mission) which was flown in February 2000 is the first mission using space-borne singlepass interferometric SAR. In this mission first simultaneous dual-polarizati...
In the present paper, the position and elevation accuracy assessment of SRTM C-band DEM (90 m resolution) has been evaluated. An accurate aerial photogrammetric DEM and orthophoto have been used as r...
