Quality assessment digital elevation models
A number of published stereo matching algorithms have been implemented and tested on SPOT images of areas for which we have gridded digital elevation models (DEMs) available with spacings of 80m or less as well as ground control checkpoints. Results will be presented for a comparison of stereo matched output with the DEMs and an analysis of the errors arising and their causes. Results will be d...
متن کاملEffects 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...
متن کاملEnhancing Textured Digital Elevation Models Using Photographs
We present a method for enhancing the visual quality of existing digital elevation models textured with orthophotos, using a sparse set of unordered, high resolution photographs. After an initial manual selection of correspondence points, we automatically register the input photographs to the given terrain data set using robust imagebased modeling techniques. To combine the geo-registered image...
متن کاملFusion of Digital Elevation Models Using Sparse Representations
Nowadays, different sensors and processing techniques provide Digital Elevation Models (DEMs) for the same site, which differ significantly with regard to their geometric characteristics and accuracy. Each DEM contains intrinsic errors due to the primary data acquisition technology, the processing chain, and the characteristics of the terrain. DEM fusion aims at overcoming the limitations of di...
متن کاملMeasuring Slopes of Gully Fan Apices Using Digital Elevation Models
Introduction: Martian gullies are defined by [1] to be slope features comprised of an upslope alcove, a midslope channel, and a downslope depositional fan. Due to their relative youth and similarities to waterrelated features on Earth, the Martian gullies have attracted much attention since their discovery by the Mars Orbiter Camera [1]. Many erosional agents for the gullies have been proposed ...
