Abstract

The effects of digital elevation model (DEM) resolution on raster and vector terrain data are investigated for the computation of hydrological terrain-soils indices. Tests of the sensitivity of the computed differences in a TOPMODEL-based watershed model reveal greater effects of resolution in the grid-based methods than the contour-based methods. Topological problems are found in all approaches specifically in the representation of stream channel and the area immediately around the stream channel
