2COGO
2.1 Overview
Description COGO is an application program to perform coordinate geometry calculations such
as
The calculations can be made from
• existing point data in the job, known distances or known azimuths.
• manually occupied points.
• entered coordinates.
)Changing coordinates of a point which has been previously used in COGO does not
result in the point being recomputed.
COGO calculation
methods
The COGO calculation methods are:
Distances and
azimuths
• coordinates of points. • distances between points.
• bearings between points.
• Inverse. • Arc calculations.
• Traverse. • Shift, Rotate & Scale (Manual)
• Intersections. • Shift, Rotate & Scale (Match Pts)
• Line calculations. • Area Division
Type of distances: The choices are
• Ground
•Grid
• Ellipsoidal
Type of azimuths: The azimuths are grid azimuths relative to the local grid.
