Thanks you Antonio,
in my present case, half a cell offset did not matter in any way, but I
notice your modification.
Your script might be well appreciated in the community
My suggestion was to complete the v.to.rast module so it could handle 3d
geometries (3d polylines and faces), unfortunate

There is no need to v.to.points isolines before rasterizing them for
nnbathy. Unless you want to generaliz
Hi Maciej,
Thank you for your reply.
I tested your suggestion but the process was /very/ long (v.trianlge
output was roughly 500 000 triangles). Perhaps a wiser solution would be
to v.to.point (i) contour lines, (ii) breaklines, then merge them in a
single raster an run r.surf.nnbathy.
Finally I

Would anyone help me figure out how I could perform this conversion,
given that I would rely on a linear interpolation method within
triangles faces (the result would be close to what r.surf.nnbathy does,
except nor this addon does support breaklines)
Hello,
trying to generate a DEM from a photogrammetric vector input file
(elevation points, contour lines, and breaklines), I decided to run the
v.triangle addon. The main reason is the local topography has many
ridges and deep gulleys and I want to incorporate a breaklines vector
map in my interp
