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.
Hi Maris,
Many thanks for the advice. Further, i am going to use r.surf.contour to
generate a raster elevation DEM for viewshed analysis. The grass vector
contour layer that i have needs to be converted to raster contour. For this
i tried using v.to.rast function. Elevation field of contour layer
As it says. You have mistyped column name. Check column name and then try again.
Still in Your case I would try to interpolate with v.surf.rst first
and then use result for analysis.
Maris.

Thanks. I have not mistyped column name. In GRASS 7 that is what you get.

Hi all,
have two shape files containing height information of a certain area. One
file consists of height information in contours (isolines) and the othesr
file consists of height information with spot heights. In order to create a
complete DEM i need heights of both layers. I need to create a
