I am using osg::EllipsoidModel::convertLatLongHeightToXYZ() method to convert the coordinates as such:
osg:::EllipsoidModel em; em.convertLatLongHeightToXYZ(_lat,_long,_alt, x,y,z); when building the model I used osgdem with the following parameters: osgdem --geocentric -d dted_dir -o terrain.ive dted_dir contains dted files in a certain directory structure defined in dted-standard. I checked the validty of the dted with a commercial software, the geographic ranges are consistent with osgdem without --geocentric parameter (I looked at the contents of the height field of the first subtile: lod=0) so there is no problem with the input file, I am sure of that. -deniz ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=35199#35199 _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
