Craig, thanks for the answer. I have found that Qgis is not using 'towgs' only if using one of the projections from installed projection database. If I create custom projection by 'Settings -> Custom CRS' it is working correctly. To get things more clear, I am inserting missing projection (see #4945) to internal database before building. This projection is using 'towgs'. -- Ivan Mincik _______________________________________________ Qgis-developer mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/qgis-developer
