6.4 By Coordinates

Instrument Height, Prism height and the names of the Standing Station and Control Pt. should be entered in this option.

The data outlined below is shown for each observation:

Project Data: Distance and theoretical horizontal angle between base and reference station, as well as height of reference station.

Measured Data: Distance and horizontal angle measured between the base and reference station, as well as the height measured.

Differences: Distance, horizontal angle and height differences between the theoretical and measured data. It is important to ensure that these values are reasonably small to ensure the orientation is correct.
