[GRASS-user] r.watershed multi flow direction

GRASS GRASS user
1

Hi,

I am using GRASS 6.4.0RC5+39438 (downloaded from svn server). I would like to obtain basins and stream segments from digital elevation data using the multi flow option in r.watershed as proposed in the documentation. The installed version of r.watershed obviously doesn't support this feature:

Sorry, <f> is not a valid flag
Sorry, <convergence> is not a valid parameter

Is there another version of the program available supporting this function?

Thank you in advance,

best regards,

Kristian Förster

I believe that MFD in r.watershed is in versions 6.5 and up.

Thank you all for your help. The new r.watershed version (GRASS 6.5) works fine and it's very fast :wink:

You need to update your 6.4 installation. It has been backported by Markus Metz
3 weeks ago:
http://trac.osgeo.org/grass/changeset/42121

A simple
svn up
in your source code directory should get all updates for you.
