What I meant is that looking at projected coordinates (screen position) in a scheme like this, one will get values in the same zone as the center. These are valid, but are not necessarily the values that would be obtained by converting to geodetic and back, choosing a zone anew. Either approach seems legitimate in terms of display. _______________________________________________ Viking-devel mailing list Viking-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/viking-devel Viking home page: http://viking.sf.net/
