Digital elevation model (DEM) generation using the SAR interferometry technique
Arabian Journal of Geosciences, 2012The development of satellite technology is rapidly increasing the evolution of remote sensing. Satellite images give extensive useful information about the land structure that is easily manageable in the process of generating true, high-speed information which allows the forecasting of future environmental and urban planning.

Digital elevation model (DEM) generation and accuracy assessment from ASTER stereo data
International Journal of Remote Sensing, 2005Digital elevation models (DEM) are the indispensable quantitative environmental variable in most of the research studies in remote sensing. The improvement of sensor and satellite imaging technologies enabled the researchers to generate DEM using remotely sensed data. These data can be started to use as not only the two-dimensional (2-D) but also three-

Influence of DEM (Digital Elevation Model) Resolution in Geomorphological Modeling
Paripex - Indian Journal Of Research, 2012We investigate whether an improvement in spatial resolution of DEMs (Digital Elevation Models) always leads to an improvement in the results of geomorphological models. To this end, we selected a state-of-art model for the prediction of soil thickness and we applied it in a test area using input data derived from DEMs with a cell size of 5, 10 and 20 ...

Based on Digital Elevation Model (DEM) for Farmland Landscape Pattern
International Journal of Smart Home, 2016Taking Gongyi city as a study area and by using the ArcGIS software, this paper analyzed the characteristics of farmland landscape patterns at the five slope gradients by Digital Elevation Model（DEM）, and explored the human disturbance on farmlands. The results indicated that the distribution of farmland landscape elements differed obviously with slope

A MATLAB-based digital elevation model (DEM) data processing toolbox (MDEM)
Environmental Modelling & Software, 2019Abstract A MATLAB-based digital elevation model (DEM) data processing toolbox called MDEM is built upon an improved DEM data processing algorithm, known as the PDEM, for rectifying flat areas and depressions in DEM data and producing realistic patterns of flow accumulation and extracted channel networks. Compared to the original PDEM, the computation

Quality Assessment of Globally Available Digital Elevation Model (DEM) for Mountainous Region
Journal of Geographical Studies, 2021The study assessed the accuracies of globally available Digital Elevation Models (DEM’s) i.e., SRTM v3, ASTER GDEM v2 and ALOS PALSAR DEM with respect to Topo-DEM derived from topographic map of 5m contour interval. 100 ground control points of the elevation data were collected with the help of kinematic hand held GNSS (Global Navigation Satellite ...

An evaluation of digital elevation models (DEMs) for delineating land components
Geoderma, 2014Abstract Land component boundaries often coincide with transitions in environmental land properties such as soil, climate and biology. Image segmentation is an effective method for delineating terrain morphological units from digital elevation models (DEMs). This paper compares the land components derived from five DEMs.
