COGO
Overview
COGO is an application program to perform coordinate geometry calculations such as
•
coordinates of points.
The calculations can be made from
•
existing point data in the job, known distances or known azimuths.
•
manually occupied points.
•
entered coordinates.
In contrast to hidden point measurements within the Survey application program, COGO is
more of a calculation program than a measuring program.
Changing coordinates of a point which has been previously used in COGO does not result
in the point being recomputed.
The COGO calculation methods are:
•
Inverse.
•
Traverse.
•
Intersections.
•
Line calculations.
•
bearings between points. •
•
Arc calculations.
•
Shift, Rotate & Scale (Manual)
•
Shift, Rotate & Scale (Match Pts)
•
Area Division
GPS1200+
distances between points.
