Tony, In answer to your question, you want to do the former. Assuming you have a geocentric database, you must convert your lat,lon,elev to a geocentric X,Y,Z (i.e. origin is the center of the earth) and then use these coordinates to set the position accordingly...
Osg::Matrix position;
earth->computeLocalToWorldTransformFromLatLongHeight(osg::DegreesToRadians(l
at),
Osg::DegreesToRadians(lon), elev, position);
transform->setMatrix(position);
"transform" is the node that is part of the entity class I discussed
earlier. If you want your entity to move along, you'll need to update the
code above in an update callback...

Hi Shayne,
Excuse my newbie status so how do I set up the MatrixTransform do I just
use the latitude, longitude and altitude as a translation or do I just set
the position of my vehicle using the latitude, longitude to set the position
of the vehicle some how.
