Hi, I have an an already mapped area of 400ha of Invasive species but the budget only allows me to work only 85ha. I wonder if there is a tool that i can use to create the 85ha polygon from the original 400ha.
You've got to ask yourself the question: Which 85 is this tool supposed to carve out?
I suggest you build yourself a polygon feature class based on a sub-area of your study plot. Edit it until you get the 85 acres you want and use it to erase or union with the original.
Draw a polygon that is 8500 x 8500 meters or what ever dimensions you want to make it 85 hectare's
Then copy the attributes from the old polygon to the new polygon.
You can easily make a perfect polygon of given dimensions by first making it with the COGO tool and then make your Polygone by snapping to the ends of the COGO lines.
