Kaarigar,
The XYZ driver is
Thanks, Frank. I am not familiar with the gdal development at all. But I
think replacing the driver binary with this new one wit your change should
fix the behavior locally for me?

OK, I have reworked the xyz driver a bit. The change is at:
http://trac.osgeo.org/gdal/changeset/24402
It should be possible to retrofit the driver into older version. Code at:
http://svn.osgeo.org/gdal/trunk/gdal/frmts/xyz/xyzdataset.cpp

Folks,
I have discovered Even already implemented my idea for XYZ and AAIGRID
19 months ago. Based on that I don't know why you are seeing a large
wait on closing.

hmm, I see a reference to 1.9dev - perhaps that was an old 1.9 pr
It should be possible to specially implement the CreateCopy for XYZ
format to avoid this. I'll investigate this.

That explains it - the XYZ file created is ~4gb in size - it would take it a

Thanks for the suggestion. I tried to convert GeoTIFF to jpg - and there
wasn't the problem. Then I tried to convert a small GeoTIFF (20 mb) to XYZ -
it still waited for some time (~10 secs) after displaying the "Done."

Kaarigar is using gdal_translate on Windows 7 64 bit from Geoinformatica
stack, which I've compiled with MingW/MSYS on Windows 7 32 bit.
I just tried similar command line on Windows Server 2008 R2 64 bit and I

I can convert a single image to XYZ from command line. And can also convert
multiple images to command line via batch file - if I press CTRL-C after the
conversion for one file is 100% done - it will continue to the next file.
There are no errors or warnings. The conversion to XYZ is successful. I
More questions? Can you convert one image into an xyz? It sounds like you
can. Are there no errors or warnings?
