I guess so because you said that r.stream.extract works with the unweighed accumulation map. How exactly did you calculate the weight?
Markus, r.param.scale in=dem_10m out=tancurv5 size=5 param=crosc r.param.scale in=dem_10m out=tancurv7 size=7 param=crosc r.param.scale in=dem_10m out=tancurv11 size=11 param=crosc r.mapcalc "weight = if(tancurv5 < 0, -100 * tancurv5, if(tancurv7 < 0, -100 * tancurv7, if(tancurv11 < 0, -100 * tancurv11, 0.000001)))" /* The r.mapcalc command is on a single line; wrapped here. */ r.mapcalc "dem_10m.acc.w = dem_10m.acc * weight"
BTW, I checked the example script in the manual of r.stream.extract and it works in 6.4.3 and 7.0.
With the Spearfish data set, correct? I could extract my data (dem_10m) and send that for testing purposes. I'm using 6.5svn. Rich _______________________________________________ grass-user mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/grass-user
