Thank you Robert.

My earlier messages sent at different times in the last weeks and I solved most 
of them at time period. Also, moderator has just approved all my messages :).

In the current situation, I am facing coordinate system problem. I am using 
geocentric terrain and geocentric coordinate system in order to show vehicle on 
the correct coordinates in the debriefing application. All geographic (lat, 
long and alt ) coordinates recorded on vehicle.  

I have no problem on terrain displaying but the transformation is not smooth 
because of higher value of the coordinates. World coordinates which are 
obtained by "computeLocalToWorldTransformFromLatLongHeight" are very high 
values. I try to convert recorded object coordinates according to a origin 
point and transform terrain to this origin. But terrain and object is not 
correlated.   

- How can I use middle coordinate system for object and terrain transformations?

Thank you!
Regards.
