[GRASS-user] snap point to line/break line at given points

[Johannes Radinger]

Hello,

I have a line-vector (river) and some points on that line. First I am straightening that line with v.generalize (method: boyle). Now, there is the problem that the points are not exactly on the line anymore. So I want to snap (move) the points to the new generalized line again. Which tool is able to do that?

After that I want to split the line at these points and want to give the attribute value to the newly created segments. These segment values should represent the number/value of the upstream point (which was used to split). How can this be done in GRASS?

Do you have any ideas to solve these two problems/challenges?

thank you
