38.5 COGO Calculation - Traverse Method
Elements that must be known are
•
the coordinates of one point.
•
the direction from the known point to the COGO point.
•
the distance from the known point to the COGO point.
•
offsets, if necessary and configured.
The coordinates of the known point
•
can be taken from the job.
•
can be manually measured during the COGO calculation.
•
can be entered.
The direction from the known point to the COGO point can be an azimuth or
an angle.
Points with full coordinate triplets and position only points can be used. Posi-
tion only is calculated, height can be typed in.
A COGO traverse calculation can be calculated for
•
a single point.
•
multiple points. Several single points are calculated in one sequence.
•
sideshots.
