not quite sure what are you trying to do?
maybe:
v.drape:
Converts 2D vector features to 3D by sampling of elevation raster map.
(https://grass.osgeo.org/grass82/manuals/v.drape.html)
Additional verti
Hello,
Thank you for your message. But I don't think it helps me.
I want to add a bridge elevation to my DEM. So if I create a 3d vector
line (my bridge) with two vertex at x,y,z coordinates, and is it
possible to convert in a raster where each cells crossed by the line
inherits of his extrap
Hi Franck,
I would suggest you to do sth as follows :
- if necessary add vertice along your 3d lines (v.split ?) so their
"density" is roughly equivalent to (or better smaller than) your target
raster resolution ;
- turn your vector lines to points using v.to.points (with use=vertex
argument) ;

Hi Vincent,
Yes it' works ! thank you for the trick

Frank

Hi
Could you use the line to select the raster dem cells, then use the center of
the selected cells to snap back to your line and use these snap coordinates to
proportion the zvalue of the snapped line segment?
