9.8 COGO
9.8.1 Starting
COGO is an application used to perform coordinate geometry calculations such as, coordinates of
points, bearings between points and distances between points. The COGO calculation methods
are:
•
Inverse and Traverse
•
Intersections
•
Offset
•
Extension
1. Select Program (2) from the Main Menu.
2. Press the PAGE key to display screen 2. Select COGO (7) from the Program menu.
3. Complete application pre-settings. Refer to "8 Applications - Getting Started".

9.8.2 COGO Calculation - Inverse Method
1. Select Traverse&Inverse (1) from the COGO menu.
2. Select Inverse (1).
Use the Inverse subapplication to calculate the distance, direction, height difference and grade
between two known points.
Known
P1 First known point
P2 Second known point
Unknown
a
Direction from P1 to P2
d1 Slope distance between P1 and P2
d2 Horizontal distance between P1 and P2
d3 Height difference between P1 and P2
