Dear all, I extracted drainage from DEM using r.stream.extract using several thresholds. I don't know why I can export the vectors generated using some threshols (50 and 1000), but for others (500 and 2000) I get error messages (Bad file descriptor: Files) when exporting with v.out.ogr .... To complicate a little bit more, the same file I exported without problem (threshols=50), I don't know why I get the same error message (Bad file descriptor: Files) when trying rasterized the heads using: v.to.rast input=My_vetor_th0050 output=My_vetor_th0050_HEADS type=point use=attr column=type_code
I am running all this under Windos 7. Any help are welcome. cheers milton
