Actually you *can* create a raster stream order map based on strahler without an accum input. i.e.: r.stream.order --o -a streams=str dirs=fdir elev=dtm_full strahler=str_strahler memory=1500 works fine ??? in_acc_opt->key = "accum"; /* required if strahler stream order is calculated for existing stream network */ in_acc_opt->type = TYPE_STRING; in_acc_opt->required = NO; /* for now; TO DO: is planned to be optional */ in_acc_opt->answer = NULL; in_acc_opt->gisprompt = "old,cell,raster"; in_acc_opt->description = "(Not recommended) Name of accumulation file (r.watershed or r.stream.extract)";I believe that you will need to get the accumulation map from r.watershed first.
