The assignment of drainage direction over flat surfaces in raster digital elevation models
Comparison of the regional approach with that using high resolution digital elevation models
and WEPP simulations on individual flowpaths showed a deviation of 19.
Incorporating the locations of true streams and legitimate sinks into the digital elevation model
generally improved the results of automated watershed delineation (Arrington, 2003).
Coupled with slope phase data generated from a digital elevation model
, more objective soil maps that better define the soil-landscape relationship can be created.
The TanDEM-X Digital Elevation Model
facilitates the interpretation of landscapes with exceptional detail, which is essential for military engineering projects and operational planning incl.
The slope map of the research area is generated from digital elevation model
using ArcGIS 10.
For this calculation, profiles are established for the main directions from the central cell 'lookup distance', L, which was extracted from the digital elevation model
(JASIEWICZ; STEPINSKI, 2013).
Perceptions of Digital Elevation Model
Uncertainty by DEM Users.
Assessment of the influence of interpolation techniques on the accuracy of digital elevation model
The geospatial data used for this study was a five metre interval Digital Elevation Model
(DEM), which is highly accurate and is available with the NSA for the whole country," Deshmukh said.
In the first instance, remotely sensed data such digital elevation model
data have been used as ancillary information, because the soil-forming factor of elevation leads to the movement of salts into lower lying, arid landscapes (Bilgili 2013) or can account for saline conditions in estuarine environments (Huang et al.
