Positional accuracy of the drainage networks extracted from ASTER and SRTM for the Gorongosa National Park region – Comparative analysis
Digital Elevation Models (DEMs) are useful for a great quantity and diversity of applications, namely for hydrologic studies that require the identification of hydrographic basins and water lines. Basins’ boundaries and the hydrographic network can be automatically extracted from DEMs, therefore their accuracy is influenced by the DEMs accuracy. Hence, it is important to control the influence of DEMs errors over the features extracted from them, since differences may be found that influence the basins’ management and/or the modeling of other phenomena.
