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
