Mapserver should handle the case. I would use the original MrSID as a source, it should work out-of-the-box. If converted to GeoTIFF first, be sure to create a tiled tiff (-co TILED=YES) and then create overview layers with gdaladdo. If you still have troubles send mail to Mapserver-users mailing list and you will be helped. -Jukka Rahkonen- _______________________________________________ dev mailing list [email protected] http://lists.openstreetmap.org/listinfo/dev
