9.7.3 Computation Procedure
Description The measuring procedure automatically determines the method of evaluation,
for example resection or three point resection.
If more than the minimum required measurements are performed, the proce-
dure uses a least squares adjustment to determine the 3D position and aver-
ages orientation and height measurements.
• The original averaged face I and face II measurements are used for the
computation process.
• All measurements are treated with the same accuracy, whether these are
measured in single or dual face.
• Easting and Northing are determined by the least squares method, which
includes standard deviation and improvements for horizontal direction and
horizontal distances.
• The final height (H) is computed from averaged height differences based
on the original measurements.
• The horizontal direction is computed with the original averaged face I and
face II measurements and the final computed plan position.
