Hi,
I have two 2D vector layers; spot heights and contours. Both represent elevation with an attribute field (say: level).
Now i need to combine both vectors into one vector so that i can use combined vector to generate elevation raster.
What is the best method to do that?
Cheers, Brian.
You are looking for v.patch
As I know Your next questions, here are answers for them:
You must set up region before interpolating with g.region. Use vect
option to limit boundaries and res to set desired resolution.
Don't forget to use -e option for v.patch to join attribute tables
too. They must have identical structure.
Interpolation tool You want to use is v.surf.rst.
Please, take Your time to read that *fine* manual. And don't skip
"introduction to ..." parts!
