hi
The wrml i have is 3d model of cave, i created ascii file and i imported it in
to grass (but only points),
but i found a way to import this in to grass. First, import to blender and
export to .dxf and then import .dxf in to grass (v.in.dxf).

Hello
This is a rather peculiar fault, which I assume is linked to X-display
settings or something similar. Here, students wanting to use GRASS use
an NX-client on a Windows PC to connect to a centrally-managed server,
and run GRASS 6.2.2RC1 on a Redhat EL machine. One of them has reported
probl
Just an idea:
v.surf.rst/idw/etc for both datasets
r.mapcalc diff=old-new
cell area*diff sum

Hello,
any idea why v.db.select works while db.select fails when invoked from inside
the same mapset?
I call db.connect -p before calling (v.)db.select and get:
driver:odbc
database:3drov
schema:(null)
group:(null)
This all works fine for v.db.select but db.select fails with an error messag
Sébastien,
could you try ogrinfo on that data set? Just to see if it also
fails. Should be something like
ogrinfo ODBC:user/[EMAIL PROTECTED] table

In man r.in.xyz!
Yep, I have to read more before posting questions ;-P

Hello Markus,
I just tried ogrinfo --formats and ODBC is not in the list :-O
Apparently, the guys at SuSE who made the RPM didn't bother to compile OGR with
ODBC support... I might as well build it all myself if that doesn't mean
spending all day downloading and building tonnes of dependenci
I have a road network where I want to convert the road lines into
boundaries, then turn the resulting spaces inside of roads into areas.
Converting the roads to boundaries was no problem using v.type and
v.clean tool=snap, but getting centroids into the polygons is
trickier. Apparently, v.c

And then of course the rest with v.centroids

Not sure but I suspect the "break" tool is what you might need.

Hi list,
My apologies if this question fits better in the developers list.
I'm trying to understand how db_fetch works and why am getting a strange error.
After a query is executed and db_open_select_cursor is used, db_fetch is used
to fetch the data of the resultant query. AFAIK, db_fetch(&curs
