• We can get the real world elevation value in [m] of any point on the terrain using three modes :

-Elevation:  Real world elevation on the ground        

-Height:     Height from the ground

-Altitude:   Real world elevation + Height

• When we want to set a position of a gameobject using a real world coordinates we also need to set the height (Elevation) in [m]   +   Elevation Mode :

-OnTheGround:  Set the gameobject on the ground (Height = 0). 

-RelativeToTheGround :     Relative to the ground 

-RelativeToSeaLevel :   Relative to the sea level
