How to split an area into two areas using PC-GPS

“Also i wanted to know if there is a way to find different sets of acres in a field that i gps’d and loaded into CMT. For example if i have three plantings in a field and for the first one i need to find about 5 Acres. Is there a way for the program to help me find the splits just by inputting the acres I’m looking for in a particular field i gps’d or no?”

With your PC-GPS 9 you can have an area split with a specific size for one of the two pieces. The function is COGO – Hinge Cut. Enter the desired acreage (5 acres) then select the node on the perimeter where you want the cut to start. Hit the “Solve” button. If the cut area is on the wrong side, then switch from Previous to Next for “Include Point in List”. If the cut looks good, hit the “Store” button. This will create a new Point.

You can then add an area of 5 acres by snapping to the relevant nodes.

Alternatively, you could use Edit – Insert Node to add a new node to the original area at the Hinge Point then use Utilities – Disconnect Areas to Sub Areas to divide the original area into two areas.

The COGO functions are also provided by PC-MAPPER 9, PC-MAPPER AI 4, CMT-SURVEY 9 and CMT-Forester 10.
