  I think this ais all you need to do:

http://docs.osgearth.org/en/latest/faq.html#common-usage


GeoTransform* xform = new GeoTransform();
...
xform->setTerrain( mapNode->getTerrain() );
...
GeoPoint point(srs, -121.0, 34.0);

xform->setPosition(point);


  So, the X and Y coordinates are either the latitude and logitude (if your
SRS's system is geographic) or X and Y (usually meters from the system's
origin) if it's a projected SRS.

  Does that answer your questions?

  If you have more questions, feel free to email me privately, as I don't
always see osgEarth questions on the OSG mailing list.


Cheers,
