I find that there are many programs that switch between autocad and google earth.
But I can not use them in Vietnam because Vietnam uses a separate coordinate system that is VN 2000
Article 1. Now use the system parameters to switch between international coordinate system
WGS-84 ( zone 48 and 49)coordinate system of national and VN-2000 is as follows:
1. Parameter shifts the origin:
-191.90441429 M; -39.30318279 m; -111.45032835 m.
2. The coordinate rotation:
-0.00928836 " ; 0.01975479" ; -0.00427372".
3. Scaling length:
k = 1.000000252906278
Article2: With each province using a separate axis
