Hey Mate,
you know, simple dipping surfaces are easy, r.plane will do the job,
but _complex_ dipping surfaces (like real faults) are still a work in
progress..

Hey pal,
does that method allows for representation of dipping surfaces?
You know you should think about that too =]

Hi grass users,
i'm trying to export a grass vector and generate a shapefile using
v.out.ogr. the vector contains 4 points and 6 boundaries each has its
own centroids.
the output shapefile contains 4 objects out of 10. WHY? How can I get
all the objects?
(i created the vector using v.patc
Thanks Soren, I got the effect I wanted in Paraview, using the "linear

Yes.
In addition to IDW, you can use RST for interpolate points and
generate a raster surface.
First all, set appropi

Sounds like a good approach.

You don't need that, define layer=0 to use z-coordinates directly.

Hi,
I was wondering if there is a way to perform the following:

Hi Gabriele,
using r.mapcalc and the @-operator within the calculation you have access to the
labels, but in IF statements it works only on labels that starts with a number
(int vals). So looking for a string is not possible.
But why not using the cats or int labels(with @) in mapcalc, then asigni
Ciao Christian, Ciao Miltinho
I tried r.cross and is useful. The problem however is that you may need to
concatenate values other than categories (eg .. values with letters A, B, C.
..). In addition, I am working with a script in BASH within a cycle and maps

Hi Carlos,
how about using v.delaunay?
If you have two lines for each fault, you can triangulate the space in between.
But im not sure if this works with vertical lines.
If you export those lines to VTK, you can triangulate vertical planes
with the VTK delaunay triangulator in ParaView.
