Flow direction toolkit: Matlab scripts for flow direction corrections
Software for manually correcting flow directions derived from a DEM using GIS tools such as ArcMap or GRASS GIS. Plots flow directions along with river centerlines and allows the user to make manual corrections.
flow direction raster, river centerlines shapefile, gauge coordinates (optional)
Follows the VIC routing model (Lohmann et al., 1998) convention for flow directions. See http://www.hydro.washington.edu/Lettenmaier/Models/VIC/Documentation/Routing/FlowDirection.shtml
