COGO Calculation - Inverse Method

Inverse Point - Point

The direction, the distance and the coordinate differences between the two known points can
be calculated depending on the data available for the known points. Points with full coordi-
nate triplets, position only points and height only points can be used.
Elements that must be known are
• coordinates of two points.
The coordinates of the known points
• may be taken from the active job.
• may be manually occupied during the COGO calculation.
• may be entered.
