Gordon, Do you have any sample output for this projection "trick"? It sounds like something I've been after for a few years now, and for the same use as you, with PROJ.

"Gord's Coords" they called it. You can set the parameters such as: <Projection Code="OSTEROUS"> <LatitudeOfOrigin>49.2124055555556</LatitudeOfOrigin> <LongitudeOfOrigin>-122.917591666667</LongitudeOfOrigin> <FalseEasting>506001.915</FalseEasting> <FalseNorthing>5451071.504</FalseNorthing> <MapScale>1</MapScale> <ScaleReductionFactor>1</ScaleReductionFactor> <CombinedScaleFactor>1</CombinedScaleFactor> <UnitsCode>METER</UnitsCode> <UnitsScaleFactor>1</UnitsScaleFactor> <P1>-39.5</P1> The most important part was the P1 parameter (or rotation). I used this technique for printing with the Dynamic Authoring Toolkit. I have defined this in Autodesk Map 3D and ported the CSD files over to MapGuide in the past, but I would love to the PROJ WKT definition for this if anyone has it... -- View this message in context: http://osgeo-org.1803224.n2.nabble.com/How-to-rotate-the-map-tp5207976p5208726.html Sent from the MapGuide Users mailing list archive at Nabble.com. _______________________________________________ mapguide-users mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/mapguide-users
