[gdal-dev] Re: gdal_translate waits at the end of operation

[Frank Warmerdam]

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

Best regards,
