Hi Andrea,
Just a note of warning:
if you have a point x,y that is inside the hole (so it doesn't belong the
the polygon), and you run some point in polygon query (intersection for
example) you will get that it is no part of any polygon but if you
convert the ring in two polygons using this m

Frank:
I turned on CPL_DEBUG in my apache local configuration file and
re-started the server. However, I am getting no other messages.
Incidentally, I am posting messages to the mapserver-users list with
respect to my problem of displaying 3-band images.
Thanks for your help.

I maintain the GDAL Java bindings, but the image-io GDAL plugin is another

I would like it to output in degrees. If there an option I can specify
on gdal_translate to put it in degrees?
Or is there another utility such as gdalwarp which will do the conversion.
You said it: gdalwarp is how you would reproject a image to a different
SRS, say from UTM to lon-lat.

Hi
I'm new to gdal so please forgive me if this is a really dumb question.
I'm running a file through the command line utility gdal_translate.
Everything works as I expect except the corners of the equirectangular
grid are in Northing/Easting.
I would like it to output in degrees. If the

No idea here. Maybe an older version of this or that?

Ah, good advice hobu. I had set ogr.UseExceptions() in my real code, but

Sure. It's a zip code area for Arizona, just some SHP I grabbed off

Matt,
Since nobody else more knowledgeable replied and I was in the original
discussion, I'll take a shot.
To review: for some situations and formats, the following code would work:
statistics = band.GetStatistics(False, True) # Force calculation of
statistics
band.SetStatistics(*statistics)
Helm,
Have you used the Microsoft Process Monitor. That could help.

Hi all,
I have downloaded gdal-1.7.3 and build this via VS2008 succesfully. Furthermore
I created an evironment variable GDAL_DATA that points to my location of the
folder "gdal-1.7.3\data".
I copied the gdal17.dll towards my release location of my VS2008 application
that will use this dll and

If it does not matter to use some other tool than OGR, OpenJUMP can explode

Hi,
I am one of the GDAL co-maintainer for Fedora, I would like to have
the image-io extension support, currently it been supported through
the following patch from image-io. But I dont think this is a good
idea as the modifications are bit heavy.

Hi Gregor
your code is correct. I think it may be related to your
dataset/feature geometry: could
you kindly provide the wkt of the geometry that is failing (print
