Hello.
Does any one know if there is a way to get texture areas instead of/or together
with a color?
I tried to use psmap, and that work in a way, but it resulted in other problems.
I have also tried qgis with grass plugin, which have good support for different
textures, but I could not set a
Hi,
I have a vector layer of 10 polys and have noticed some odd behaviour.
There is a long delay of a couple of minutes on opening the attribute table
(i'm accessing (Postgresql/postgis locally at present). Also when the layer
is open applying a simple query in the attribute table manager
I am trying to import some data in GRASS and have run into a problem. I hope
someone can give me a little insight to help out.
I downloaded some aerial imagery from here:

MrSID files are a bit tricky. This is a proprietary format owned by LizardTech
(see http://www.gdal.org/frmt_mrsid.html). That being said, they freely
provide decode tools at their website (http://www.lizardtech.com/). Working on
OS X, I use their Raster_DSDK in a little command line routine
I am also working on OS X. But, I am using the MrSID plugin, from William
Kyngesburye. So it seems that both gdalwarp and r.in.gdal are willing to
import it. But, maybe I will try to search around for the apps that you are
referring to, to see if they might do a better job on the conversion.
I'm not familiar with the Kyngesburye plugin and haven't used gdalwarp, but

Hmm, something I've seen for a while (Mac only), and it didn't improve with the
latest MrSID DSDK, is that there are errors in retrieving GCS info from a sid
with GDAL - some parameters are reported wrong or dropped. It hasn't been a
problem for me since I usually know the projection of the

I read that all of Michigan, and not just Detroit, is in serious trouble

hmph, looking at the code for i.pca I'd hoped it would have
gone on for 256 characters (~30 components). oh well, at least
it didn't crash the program when it went beyond 80 chars.

I am not clear how to get useful results out of v.kernel. I have a vector
layer imported from PostGIS that has about 2.5 million points. I want to
make a high density raster to show where these points are clustered. I can
get the vector layer to display in GRASS just fine, albeit without
