GEOPAK COGO
CONCEPTS COURSE

The Coordinate Geometry (COGO) Concepts Course was developed as a self help program to aid employees of NCDOT Roadway Design Unit in the development of their knowledge of GEOPAK COGO syntax.

We found that many people experience difficulty understanding the syntax lines of COGO command lines, especially in converting existing alignments or data into input files.

The course is provided in four sections:

(1) Points
(2) Curves
(3) Spirals
(4) Chains and Alignments

By using the GEOPAK general term conventions, the exercises in each section build a foundation for understanding by assembling the various parts of a command line in the correct sqeuence. We feel confident that this course will be beneficial to anyone experiencing difficulties with COGO.


This course, available only in Word Document format, includes four instruction documents.
