Analysis and correction of digital elevation models for plain areas
(Amer Soc Photogrammetry, 2019-03)
Water movement modeling in plain areas requires digital elevation models (DEMs) adequately representing the morphological and geomorphological land patterns including the presence of civil structures that could affect water ...

Evaluation of Open Source Dems for Regional Hydrology Analysis in a Medium-Large Basin
(Austin Publishing group, 2016-09)
Nowadays exist a variety of topographic source with different spatialresolution obtained by using distinct methodologies. Choosing a data sourcethat is the more accurately possible in area relief, has become fundamental ...
Digital elevation models (DEM) used to assess soil erosion risks: a case study in Boyaca, Colombia
(Universidad Nacional de Colombia, 2016-05-01)
The objective of this research was to develop a model for assessing the risk of erosion, exploring the potential of DEMs from SRTM, ASTER, ALOS PALSAR and one made with interpolation of a 1:25,000 contour map to calculate ...
Multiscale Analysis of Topographic Surface Roughness in the Midland Valley, Scotland
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2011)
Surface roughness is an important geomorphological variable which has been used in the Earth and planetary sciences to infer material properties, current/past processes, and the time elapsed since formation. No single ...
