Carving and adaptive drainage enforcement of grid digital elevation models
[1] An effective and widely used method for removing spurious pits in digital elevation models consists of filling them until they overflow. However, this method sometimes creates large flat regions which in turn pose a problem for the determination of accurate flow directions. In this study, we propose to suppress each pit by creating a descending path from it to the nearest point having a low...
متن کاملEfficient extraction of drainage networks from massive, radar-based elevation models with least cost path search
The availability of both global and regional elevation datasets acquired by modern remote sensing technologies provides an opportunity to significantly improve the accuracy of stream mapping, especially in remote, hard to reach regions. Stream extraction from digital elevation models (DEMs) is based on computation of flow accumulation, a summary parameter that poses performance and accuracy cha...
متن کاملBuilding extraction from digital elevation models
To extract buildings from Digital Elevation Models, we define a point process whose points represent buildings. We then define a density for this point process which is split into two parts, consisting in an ”internal field” that allows us to model the prior knowledge we have on patterns of buildings in urban areas and an ”external field” that makes the point process fit the data. We then use a...
متن کاملAutomated suitable drainage network extraction from digital elevation models in Taiwan's upstream watersheds
Automatically extracting drainage networks from digital elevation models coupled with the constant stream threshold value is a regular method. These extracted networks can be verified by comparing the channel initiation points with those from real networks. From the results analysed, the differences in channel initiation points will affect the network geometries, geomorphological indices and hy...
متن کاملGeomorphometric Analysis of Maroon River by Digital Elevation Model
Digital Elevation Models (DEMs) are used to estimate different morphologies, analysis of river profile, delineating drainage basin and drainage pattern associated with lithological and structural changes. The study area is Maroon River located in Khuzestan Province, Iran. In this study geomorphometric analysis based on DEM carried out to understand Maroon river uplift rate and tectonic- erosion...
