2COGO
2.1 Overview
Description • COGO is an application program for coordinate geometry calculations such as:
• coordinates of points.
• distances between points.
• bearings between points.
• The calculations can be made from:
• existing point data in the job, known distances or known azimuths.
• measured points.
• entered coordinates.
)
COGO calculation
methods
Distances and
azimuths
• 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.
• Arc calculations.
• Shift, Rotate & Scale (Manual)
• Shift, Rotate & Scale (Match Pts)
• Area Division
• Type of distances: The choices are: Ground, Grid, Ellipsoidal.
• Type of azimuths: The azimuths are grid azimuths relative to the local grid.

Field Option Description
Points stored with point class MEAS can be
stored with the same point ID. The averaging
functionality (configured under job management) can then be used to calculate an
average for these points.
Points stored with point class CTRL can only
be stored with a unique point ID. A message
is always displayed when a point is about to
be stored with an already existing point ID.
The user can then decide to either keep the
existing point or overwrite the existing point.
<Est Pos Qlty:> User input The estimated value for the position quality
assigned to all calculated COGO points
which is used for the averaging calculation.
