Hi Umit, VPB, when generating a geocentric database, decorates it with a CoordinateSystemNode, so just find this node when you load your database then use you camera position as the XYZ to input into the EllipsoidModel::convertXYZToLatLongHeight(..) method. You get the EllipsoidModel from the CoordinateSystemNode.
