Hi all,
I'm trying to create a VRT file for a GTiff that is Int32 or Float32 to
add a ColorTable but I seem to be missing a key piece of information.
How are the pixel values mapped
I believe that OSGeo is expecting every approved student to have a
mentor and a co-mentor this year.
I have been a mentor for the last 5+ years for pgRouting. We have had 2
students most of those years and two mentors with each mentor being the
co-mentor for the other project. This has worked
Sorry meant to send this to the list.

Hi All,
First off, sorry this is really long with all the gdalinfo pasted into
it, but I thought is might be more useful to have real information to
look at.
I have been running down a problem caused by upgrading a server to a
newer version of gdal. Here are the details:

Mikhail,
This is a very interesting idea.
You might want to add specific support pgRouting which already supports
building graphs, creating routing topology and solving various graph
problem using postgis for geometry and tables for building and linking
the topology.
You might also want to

Hi,
Sorry for cross posting. This seems like a proj4 issue but might be gdal
related.

Unless something has changed, I have never been able to work with dbf

Would it make sense to create and load a stored procedure that you use
to load the feature with, then you can trap exceptions and ignore them.
I would think that this would be much faster. Well the stored procedure
is run in a transaction bout you could do something like:

Hi Even,
Frank pointed me to your blog entry on the GDAL virtual file system at:
http://erouault.blogspot.com/2012/05/new-gdal-virtual-file-system-to-read.html
This is most excellent. I am trying to get this to work using the
/vsicurl/ option to connect to a php page that generates CSV
Just a followup to this, I have downloaded gdal-1.9.2 and get the same
results. So no joy there.
