Hello, there are two options: 1st - join both datasets into single one (GRASS vectors can contain different geometries in single vector dataset) and use v.surf.rst (it will use both line and point data) 2nd - convert lines to points with v.to.points and then join into single point dataset. Interpolate with any tool.
Good luck, Maris. 2013/1/12 Brian Sanjeewa Rupasinghe <[email protected]>: > Hi all, > > have two shape files containing height information of a certain area.
