Ciao Tim,
you should probably post these questions to the geoserver users mailing list.

Hi Brent,
Unfortunately the data is already out of Postgres, so I don't have that
option anymore. I was hoping there might be some way of invoking a geos
function in ogr2ogr.
Thanks though,

In your ogr2ogr query string query try
"select buffer(area, nn.nn) as geom from table where...;"
PostGIS will buffer it before sending it to GDAL for export to shapefile.
Or if you are repeatedly doing this, create a view in PostGIS with the buffer,
& select this with GDAL, whichever sui

I too have been using Ubuntu 8.04 (Hardy) to compile and run GIS apps & libs
(grass, gdal, qgis, geos, proj, etc) and have had no problems at all.

Folks,
I have drafted a preliminary version of a new RFC for discussion.

Feedback is welcome.
Best regards,

As an institution, we prefer Fedora, although I have little experience of
it myself. It is widely supported by commercial applications, as well as
open source. I have built GDAL for Cygwin (not my primary platform, I
hasten to add!) with only issues surrounding Xerces that I have not been

I have been running a fairly complete open source GIS stack on a couple of
Ubuntu 8.04 machines for about 6 months. I have had no problems getting
anything installed from source on them, and use the supporting libs that are
available via apt-get almost exclusively. If anyone wants to see the

Hi All,
I'm trying to port some of my existing PostGIS based workflow to ogr
utilities and shapefiles. Is it possible to buffer a feature that I've
selected via the ogr2ogr "-where" clause? I'd like end up with a single,
buffered feature in a stand-alone shapefile when I'm done.
Thanks,
Roger
Hi.
I suggest you look at OpenSuse. That's my preferred FOSS GIS platform for a few
years now.
The guys that maintain the OpenSUuse GIS repository are really efficient &
helpful. The couple of times I've wanted an updated package there I've emailed
them & it's been done in a couple of days.
Hello,
I'm having trouble getting an image warped properly using GCPs. I'm
wondering if I'm missing a piece in my code.
Here I am warping from an image with a presumably unknown projection to
a georeferenced reference image. The images have been registered
either manually or automatically

hi list,
I'd appreciate suggestions on Linux OS. We'd like to build newest gdal,
as well as OpenEV2 using GTK2.
Have tried CentOS. But it libraries seem too conservative.
Is Fedora 9 a better choice?
