Hello, Thanks for your reply. Yesterday i tested Grass via SextanteFORQgis. There was a bog during the process and i had a error message.
This morning i have tested Grass via Qgis and it's works well. I have 2 questions : 1/With Grass r.watershed i have to enter this following parameter : "minimum size of exterior watershed basin" (without unit value). What criteria determines the value to be enter? How to know this value ? In my case, i 'm using SRTM 90m as DEM raster input. 2/According to you, what is the better tool between r.watershed or Taudem "StreamReach and watershed" ? Thank you in advance. -- View this message in context: http://osgeo-org.1560.n6.nabble.com/r-watershed-minimum-size-of-exterior-watershed-basin-tp5011178.html Sent from the Grass - Users mailing list archive at Nabble.com. _______________________________________________ grass-user mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/grass-user
