So this means I need to write my own application using the Union() from
GEOS and I cannot use it on the command line using OGR VRT?
That is OK, I can do that. Using existing utilities on the command line
seemed easier ;)
Thanks,
Paul

Am I missing something or isn't this available for ogr?
Thanks,

Hi Even,
I'm not sure why I shouldn't use --format. If I can't use it why is it
provided?
Can I use --formats?
Perhaps I should not handle this in my C#/WinForms but do this in our C++
core.
I think we can make a method that would return what I need based on
gcore/gdal_misc.cpp but that would rely
ng C# bindings.
Thanks,
Paul

We have compiled GDAL with GEOS so we can access those methods as well.
Thanks in advanced.

To add my 2cnts.
With MapWindow GIS we use TauDEM binaries to perform watershed delineations.
http://hydrology.usu.edu/taudem/taudem5.0/index.html
These TauDEM binaries are optimized to use MPI, but also work if you don't
have MPI installed.
I don't know in detail how it works but in general you
The last days I've been trying to convert my ecw file to a GeoTiff so I can
use it in Geoserver.
The ecw is a mozaik of aerial photos.
When I do these two commands it is working in Geoserver:
- gdal_translate -of GTiff -co tiled=yes -co compress=jpeg -co
photometric=YCBCR -a_srs EPSG:28992 -
EG --config
PHOTOMETRIC_OVERVIEW YCBCR lowres-compressed-transparent.tif 2 4 8 16 32 64
128
Thanks all.

Did I loose it along the way? Or is it expected to have such a large sized
end result.
Because it is now so large I think I'll get into trouble when I add it to
Geoserver. I hoped to use the tiff directly and not use Geoserver's pyramid
plug-in.
Thanks,

Thanks Andrea,
I didn't understand that the first time.
So there is no way to have the raster on top of another layer without
getting white areas?
In that case I will upload the smaller tiff file ;)

I did use the "input transparent color" in GeoServer and it is working
great.
I can now continue with my task.
When I'm done I'll do some more experimenting with different order of steps
and different compression to get a clean tiff.
Thanks all for your hel
lem.
Does anybody know how to solve this?
I run it on a Vista 64-Bit 4-core, with 8GB RAM. I'm getting the same error
on a WinXP sp3 2-core, with 2 GB RAM

I don't know anymore how to to this. How can I split my large ecw file into

I also noticed that even if I use the same EPSG code I get d

Hi all,
We're using GDAL and libecwj2.dll in our application: MapWindow GIS (
www.mapwindow.org)
I'm trying to compile a Win-64Bit version of MapWindow. To do that I need to
compile all supporting libraries to Win-64Bit version as well.
GDAL is compiling great, except when using libecwj2.dll. Beca
Tamas, Mateusz and Rob,
Thanks for all your help.
It seems I can now successfully build to 64Bit.
In my first attempt I replaced Win32 with Win64 in the Preprocessor
Definitions.
That gave me the "unknown machine type will require custom 64 bit variables"
error.
When I restored Win32 I got the __a
