Hi It would be a good choice having GDAL library migrating to 1.7 series - already available in experimental since ages - in squeeze. It would involve the following packages: dans-gdal-scripts libgdal-grass grass thuban qgis xastir mapserver merkaartor qlandkartegt mapnik liblas with a round of accurate bin-NMUs. Of course, RMs blessing is a pre-requirement. -- Francesco P. Lovergine
