12.4 3-D COORDINATE MEASUREMENT 

The instrument user may determine the coordinates of a target points based on the 
station and backsight data along with rod and target heights. 
 
The coordinate values of the target are calculated using the following formula. 

N1=N0+S×sinZ×cosAz 
E1=E0+S×sinZ×sinAz 
Z1=Z0+S×cosZ+ih-th
