[GRASS5] 5.1 - Vector data and elevation information

GRASS GRASS developer

I just tried the new vector modules in grass51. You have done a really good job! Congratulations. It is working very nice.

I have got a question about elevation information on a vector line. Will it be possible to store elevation information on every node of a vector line?

I have digitized some streets in 5.1. Additionally i have some point data describing the elevation information of our region. Is it possible to "merge" the elevation information into the edges of every vector line?

Thanks in advance

In general yes. Right now I have submitted an extension to d.vect
to display the z coordinate (elevation) of each node.

To do this, you need a new module which takes 2D vector and raster DEM
and generates new 3D vector. Such module does not exist yet.
