Comparative analysis of the differences between using LiDAR and contour-based DEMs for hydrological modeling of runoff generating debris flows in the Dolomites [PDF]
, 2015 Present work aims to explore the differences in hydrological modeling when using digital elevation models (DEMs) generated by points from LiDAR surveys and those digitized on the contour lines of the regional technical map (RTM) and their relevance for ...

Towards the optimal Pixel size of dem for automatic mapping of landslide areas [PDF]
, 2017 Determining appropriate spatial resolution of digital elevation model (DEM) is a key step for effective landslide analysis based on remote sensing data. Several studies demonstrated that choosing the finest DEM resolution is not always the best solution.

InSAR observations of ice elevation and velocity fluctuations at the Flade Isblink ice cap, eastern North Greenland [PDF]
, 2010 The 8500 km(2) Flade Isblink ice cap (FIIC) (81 degrees 15'N, 15 degrees 0'W) is the largest ice cap in Greenland. We use repeat-pass interferometric synthetic aperture radar (InSAR) techniques to investigate the form and flow of the FIIC.

Pre-late Devensian high-arctic marine deposits in SW Scotland [PDF]
, 2010 We present new interpretations of Digital Elevation Model (DEM) data and marine fossils collected from three sites on the Rhins of Galloway which, contrary to recent proposals, suggest that the landforms and deposits of the region do not represent ...

Model zemeljskega površja - DMR ali DMV? : Earth's Digital Surface Model - DTM or DEM? [PDF]
Geodetski Vestnik, 2002 Definition of a term digital terrain model that can be shortly described as 'digital description of the Earth's surface' was analysed. Meaning and usage of terms 'digital terrain model' or shortly DTM and 'digital elevation model' or DEM were cleared up.

3D Visualization of Large Digital Elevation Model (DEM) Data Set [PDF]
, 2002 With the rapid development of Earth observation technologies, raster data has become the main Geographic Information System (GIS) data source. GIS should be able to manage and process huge raster data sets. In this paper, the problem of 3-dimensional visualization of huge DEM data sets and its corresponding images data sets in GIS was addressed. A real-

DETERMINATION OF A TOPOGRAPHIC WETNESS INDEX USING HIGH RESOLUTION DIGITAL ELEVATION MODELS
European Journal of Geography, 2023 Topographic wetness indices (TWIs) computed from digital elevation models (DEMs) are means to forecast the amount of moisture in the soil. In this study, using sub-pixel/pixel attraction the spatial resolution of digital elevation models (DEM) was ...
