[GRASS-user] problems with v.edit

2009-01-20 Thread chiaraerc...@tiscali.it
Hi all. I have a problem with v-edit. I have to break a vector line into two parts near a point. I gave this command: v.edit map=ret_125 layer=1 type=line tool=break thresh=$ris_edit coords=$x,$y snap=no where " $ris_edit " depends on the resolution of the DEM raster map, "$x" and "$y" are

[GRASS-user] problems with v.edit - merge

I can't figure out how to solve a problem with a line feature shapefile I have. It has been wrongly created as 81 single lines touching each other with their vertexes. I need to merge the lines into a unique line. I've tried with v.edit and the merge tool, two times. First time it gave me 32 lines,

Ok I found out the problem meanwhile you were answering. I had 4 lines but three of them where very weird: 2 points, vertex to the same vertex -> a point, but stored as a line. I couldn't see it, beacuse it was superimposed on the major, single line. I think it was a problem with the original shape
