Description
1.
The procedure for a COGO intersection calculation with distance -
distance is very similar to a COGO intersection calculation with
bearing - bearing.
Follow the steps 1. to 5. in paragraph "COGO intersection calculation
with bearing - bearing step-by-step" The differences are:
•
<Method: Dist - Dist> is to be selected in COGO Intersection
Input, Input page.
•
For both known points <HDist-XX:> is used instead of
