Hi to all,
I'm trying to use GRASS 6.4 (installed on UBUNTU) to realize a system to
automate the orthorectification process.
I have a group of little images (chip of 256x256 pixel) that I want to use to
orthorectify an image.
Can grass use the little chip to create the RPC polynomial without

I have a vector map with points representing latrines and each point
has an attribute describing the place name. I ran v.edit to snap
points with a threshold of 5m and v.info reports 7296 features for the
cleaned map. I now wish to count the number of latrines in each place,
so I ran:

Dear all,
I am starting to use GRASS and I am trying to set up a location with the

First I set up the location using the EPSG code and the I tried to import a

Because you think that these points are actually duplicates, or because

My guess - that GeoTIFF data are in EPSG:3035, still GeoTIFF's
coordinate reference system is wrong or missing - i.e. it has world
file and no proj file. GRASS will generate error in such case, still
if bounds are OK, importing with -o will do the right thing.
Laura, check Your GeoTIFF file with

OK, this is strange.
I am using v.sample to determine whether a point falls inside or outside a
simple raster (only two colors - white and brown).
The vector points have only two columns in the table: cat, and an integer value
(327670) - the aim is that the result will be 0 where the point is on
Excellent! So, yes, it turns out I hit my quota on the disk server --
our sysadmin raised it, but the same error was occurring. g.region -d
worked spectacularly! Thanks!

Hi , I have a large vector shapefile I would like to split into many smaller
tiles of equal size. Can somebody suggest a way to do this in GRASS 6.4 (either
Windows or Linux).
Also is it possible to use scripts (for batch processing) under the Windows
version of GRASS?
Many thanks
George
