Hi Brede -- So it sounds like EllipsoidModel projects from lat/long/alt to a 3D XYZ coordinate in space, but what you really want is more of a standard map projection: from lat/long/alt to a 2D map XY.
This is how we used to do our 3D renderings at my previous employer, which we called the "flat Earth" model. We essentially used the Proj4 library to do all the projection we needed. (it supports Mercatur as well as other projection types.) -Paul > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] On Behalf Of > Brede Johansen > Sent: Tuesday, March 13, 2007 4:59 AM > To: osg-users list > Subject: [osg-users] CoordinateSystemNode and map projections > > Hi all, > > I'm experimenting with the osgsimulation example where a > plane is flying round the world.
