I've got vectorial data representing isolines of territorial elevation
and would like to generate an elevation map as is required for 3d
display. There is no bounding rectangle, so r.surf.* fail. Is there
another way to do this?
No real problem, I think. Digitize the area you want to have interpolated
in v.digit (basically, an outline of the isolines) and convert this to
a raster map that you use as a MASK during interpolation - if I recall
right, the area outside the MASK will not be interpolated.
Good luck,
