Viva Series, COGO 744
38 COGO
38.1 Overview
Description COGO is an application to perform coordinate geometry calculations such as
• coordinates of points.
• bearings between points.
• distances between points.
The calculations can be made from
• existing point data in the job, known distances or known azimuths.
• manually measured points.
• entered coordinates.
In contrast to hidden point measurements within the Survey application, 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.
