Jonathan, I've done this using v.distance with the upload option (to_x and to_y) to get the coordinate of the nearest place in a line close to my points. Then I'd export the to_x and to_y columns and create a new point vector file.
I've done this so I could create the watersheds for 150 pour points, snapping each point to the rivers line derived by the flow accumulation Cheers Daniel On Wed, Aug 13, 2008 at 4:33 PM, Moritz Lennert <[EMAIL PROTECTED]> wrote: > On 13/08/08 21:19, Alex Mandel wrote: >> >> Jonathan Greenberg wrote: >>> >>> I have a point file that I would like to have the points snapped to the >>> nearest line in a different vector file (preferably anywhere along the >>> length of the line, although the nearest line node would be ok) -- how do I >>> do this in GRASS? >>> >>> --j >>> >> >> v.patch can draw lines from the point to the existing network >> v.net op="connect" can put the points on the line if you need them as >> nodes for network analysis. > > or: > > v.edit with the bgmap= parameter. > > v.distance with output= parameter which creates a map of lines which you can > then v.patch. > > Moritz > > _______________________________________________ > grass-user mailing list > [email protected] > http://lists.osgeo.org/mailman/listinfo/grass-user > _______________________________________________ grass-user mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/grass-user
