Digital elevation model (DEM) generation using the SAR interferometry technique

Arabian Journal of Geosciences, 2012
The 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.

Accuracy assessment of the global TanDEM-X digital elevation model in a mountain environment

Remote Sensing of Environment, 2020
The past two decades have been prolific in production of global or near-global Digital Elevation Models (DEMs) derived from satellite data. The most recent addition to the family of global DEMs is the TanDEM-X DEM with resolution of 0.4 arc sec. DEMs are

Digital elevation model (DEM) generation and accuracy assessment from ASTER stereo data

International Journal of Remote Sensing, 2005
Digital 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, 2012
We 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 ...

Accuracy assessment of a low-cost UAV derived digital elevation model (DEM) in a highly broken and vegetated terrain

Measurement, 2019
Digital Elevation Models (DEMs) are frequently used in geology, environment, engineering and architecture related studies. Along with the technological advances, there are also improvements in the production techniques of these data.
