We will pursue this route here at Noblis where Spencer worked over the summer. Our folks who installed the gdal libraries will be in touch, probably next week as we will be out of town this week. Thanks for your quick response.

Are you in a position to rebuild your GDAL with a patch? I'd appreciate your filing a bug against GDAL/OGR for this issue, and we can pursue the discussion there. http://trac.osgeo.org/gdal/ Best regards, -- ---------------------------------------+-------------------------------- ------ I set the clouds in motion - turn up | Frank Warmerdam, [EMAIL PROTECTED] light and sound - activate the windows | http://pobox.com/~warmerdam and watch the world go round - Rush | President OSGeo, http://osgeo.org _______________________________________________ grassuser mailing list [email protected] http://grass.itc.it/mailman/listinfo/grassuser _______________________________________________ grassuser mailing list [email protected] http://grass.itc.it/mailman/listinfo/grassuser
