Hi
I have calculated the vegetation index using Grass 7 graphically and it was
done perfectly, my question is:
can I obtain a sample programming code in c language which do the same thing
without using the graphical interface ?
Or is there anybody knows which methods from Grass 7 programming

it seems that You are looking for v.db.connect, as You need to

You are careful, just edit MAPSET/vector/MYMAP/dbln file.)

What you'll have to do, as Lee pointed out [1] is use the

Hi community,
I'm trying to convert my 3 vector points to raster points. The aim is to use
this raster points as input for r.surf.nnbathy.
I created a region with following command:
g.region --verbose vect=gfa_niep_work@PERMANENT nsres=1 ewres=1
This is the output of the region:
projection: 99
Hi all
After the run the i.vi with C code, I am getting the following error:
GISRC - variable not set
and after this command:
export GISRC=$TMPDIR/$THE_GRASSRC
I am getting the next error:
Variable 'LOCATION_NAME' not set
So please any suggestion or help
Thanks in advance for
Hi Ripsime,
Are you running this script from within GRASS? It says you've got no
location set, but when you start GRASS it sets a location for the session
you're working in.

Hi there,
How are your points spatially distributed? It could that 1) the region
you're working with doesn't contain all points or 2) the resolution is so
low that the three points are aggregated to one point.
My suggestion would be to do g.region vect=gfa_niep_work to match the
region spatially
Hi Daniel,
this steps i've tried already :D
This is very confusing, one time i got 2 of 3 points (the points were
coloured like raster points). And when i try another configuration i got no
points just a white area with min/max value of one point.
The extent was always on my vector point map, i

Maris,
You may very well be correct. I have been looking
Hi Danny,
Theoretically that should be fine. I doubt that your points are less than a
meter apart. To tell the truth, I'd need to take a look at the data a bit
more to be able to say much more about it. Your command looks fine to me.
You could also try expanding the region by a hundred meters or

Asked and answered:

But, for those of us attempting new operations a cross-reference to all
relevant modules (in this case attribute database related) would be
extremely helpful.
it seems it's there, see the bottom of the manual page:

Anything I can do to prevent this?

The nviz syntax allows us to specify multiple line/area and point maps to
overlay the base elevation map. What I do not see on the manual page or in
the GUI dialog box is how to specify colors, line widths, symbols, and sizes
for these maps. Can this be done somehow?

Just updated to the latest svn version of grass 7. Configure went OK
but I got a bunch off errors on make, the first one being in
