Zeki, Don't transform the root scene (I assume you mean the terrain). Instead just take the matrix you got from computeLocalToWorldTransformFromLatLongHeight() and put that into a MatrixTransform. Then any points under that MatrixTransform are local to that world point, and you won't have any precision jittering problems.
