| Abstract | This work presents a comparison of geomorphometric variables derived from different SRTM data, namely C-band (originally 3) and X-band (originally 1), both stored under the resolutions of 3 and 1. C/1 data was refined from C/3 through kriging, within the processing for the Brazilian Topodata project. X/3data was produced by contracting X/1 by aggregating neighbor pixels and (subpixels). Derivation procedures were adapted from previously developed algorithms designed to perform the basic derivations of DEM through geometrical approach, digitally simulating the measurement of the topographic variables according to their theoretical concepts. Derivation procedures resulted in GIS (Geographical Information System) layers of the basic local variables height, slope angle, slope aspect, plan curvature, profile curvature and a thalweg-divide delineation for drainage analyses and watershed partition. Geomorphometric derivations on both C/3 and X/1 were shown to result indistinct from the point of view of numerical and spatial distribution. At the 1 resolution, a striking roughness of the X band DEM (Digital Elevation Model) was responsible for major differences in pattern and main deviations. In addition, its sensitivity to canopy effect deprived the perception of important terrain features. Otherwise, C/1, refined from C3 showed the same detail level without the undesirable disturbances described for X band. The conclusion stressed the convenience of working with X/1 rather than with X/1 when dealing with geomorphometric derivations. |
