I have one vector map consisting of 30831 points, and another consisting of a road network. I have used the v.distance function followed by v.clean to connect each point to the nearest road. I used the errors from v.clean to obtain the intersections: basically, each point's projection onto a road.
#v.distance -p from=incidents to=roads out=connect upload=dist column=dist #v.patch roads,connect,points out=patched #v.clean patched output=patched_clean err=intersections tool=break,snap The problem is, the error layer (intersections) only contains 6715 points but for my next step I need to have the same number of intersections as data points. (In the next step, I want to take this layer of intersections (points) and locate the nearest point in another layer along a road, so I need to have the same number of intersections as I have data points) What am I misunderstanding about the v.clean process? Is there some way I can fix this? -- View this message in context: http://www.nabble.com/Snapping-Points-to-Nodes-along-Lines-tp19716703p19716703.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
