I generated a 1x1 degree graticule in QGIS using the graticule plugin, set value of 1 in your dataset to be transparent and underlaid the vmap country boundaries. The BSB dataset aligns with neither the vmap or the graticule. See screenshot link below. Have you been able to verify that it is properly aligned when opening in other GIS software? http://www.flickr.com/photos/timlinux/3149590299/ Regards -- Tim Sutton - QGIS Project Steering Committee Member (Release Manager) ============================================== Visit http://linfiniti.com to find out about: * QGIS programming services * Mapserver and PostGIS based hosting plans * FOSS Consulting & Support Services Skype: timlinux Irc: timlinux on #qgis at freenode.net ==============================================
