Hi Dave,
what I did in this case, was, as you said, to convert the centroids to
points and then run v.what.rast.
One possibility to get the information to your table:
1- Convert the polygons (the categories) to raster with r.to.vect.
2- Do a v.what.rast with this raster-area map.
3- Make a

(Linux) which includes not only using GRASS' modules but adding a few ones
(simples). My idea was, at the end of the project, give an Linux

Hi list,
I'm trying to do a randomForest classification in a MODIS NDVI time
series. So far I've been able to generate the randomForest and get the
Grass NDVI images inside grass as a SpatialGridDataFrame. Then,
following some notes from Markus Neteler [1], I converted the
SpatialGridDataFrame to

Last week someone mentioned at this mailing list the r.seg segmentation from
here: http://www.ing.unitn.it/~grass/)
I have contacted the author but he didn't replied. Have anyone ever used? or
know someone that have used? :)
Please help me because I'm not able to run it
Thanks

I'm doing some tests in order to customize my winGRASS installation and I
wanted to know if I can change anything else in GUI, besides the menu
(changing an xml file)? Like menu colors, function/script forms, display
windows, buttons? If so, how can I do that?
Thanks
Best regards

On Tue,
Friends,
If I understand correctly (based on experience with my own data),
when GRASS calculates the topology for vector area data it doesn't
actually ensure that the centroid lies within the area it represents.
If the area is a torus, or at least hollow in a general way, then the

Friends,
This is the second time in two days I have had to post an apology
and retraction for hasty questions. I apologize for testing everyone's
patience. Thanks Markus; I was composing this message when I saw your
post. I mistook a centroid of a polygon too small to plot at the

It does raise a question, however, of what the conditions are that cause
d.what.vect to return a feature type of Boundary rather than Area when

d.what.vect and v.what search for points and centroids first. If none

I think it would indeed be handy if a switch was added to v.what and
d.what.vect in GRASS 7. In the meantime it might be handy to write a
v.pip command for GRASS 6. I have written a point-in-polygon routine
for other software (including R), but I would have to really study
Hi Monica,
Any suggestions of doing a stand-alone installer of GRASS plus a few modules
of my own?
just have a look at
http://trac.osgeo.org/grass/wiki/CompileOnWindows
compiling and packaging a standalone wingrass-installer isn't so difficult.

Hi Hamish,
thanks for the first hint, now it loads the list of available data.
Nevertheless, it still does not import the requested data.
I use the wxPython frontend command, there I get:

I am new user for Grass GIS. I have some questions regarding Jpg or tiff
