Creating Low-Cost High-Resolution Digital Elevation Models

Effects of Digital Elevation Models (DEM) Spatial Resolution on Hydrological Simulation

Digital Elevation Model is one of the most important data for watershed modeling whit hydrological models that it has a significant impact on hydrological processes simulation. Several studies by the Soil and Water Assessment Tool (SWAT) as useful Tool have indicated that the simulation results of this model is very sensitive to the quality of topographic data. The aim of this study is evaluati...

High Resolution Digital Elevation Models of Mars from Moc Narrow Angle

Introduction: In this abstract we report on our initial experiences performing stereotopographic mapping of Mars with high-resolution images from the Mars Global Surveyor Mars Orbiter Camera Narrow-Angle subsystem (MGS MOC-NA; [1]). Accurate topog-raphic information, and, in particular, high-resolution digital elevation models (DEMs) are of intense interest at all phases of Mars exploration and...

Refinement of Urban Digital Elevation Models from Very High Resolution Stereo Satellite Images

Digital elevation models (DEM) of high resolution and high quality are required for many applications like urban modeling, readiness for catastrophes or disaster assessment. A good source for the derivation of such DEMs from any place in the world are very high resolution (VHR) satellite stereo images as provided e.g. by Ikonos, QuickBird or WorldView. In this paper a method for the generation ...
