Improving the positional accuracy of drainage networks extracted from Global Digital Elevation Models using OpenstreetMap data

Improving the positional accuracy of drainage networks extracted from Global Digital Elevation Models using OpenstreetMap data

Drainage networks allow the extraction of topographic parameters that are useful for basins characterization and necessary for hydrologic modelling. One way to obtain drainage networks is by their extraction from Digital Elevation Models (DEMs). However, it is common that no freely available DEMs at...
