I have a 6-acrea polygon, in ArcGIS 10, and would like to make 2 3-acre polygons
Solved! Go to Solution.
If you have a Parcel Fabric, this could be an option:
Creating new parcels using divide by area
By proportional area

Do you want to do it manually once or automate the process for many different polygons? I'm guessing the polygons are not symmetrical...
Wow, pretty fast response. No, I don't have so many that I need to automate the process. I can do it manually.
Sorry, nothing comes to mind immediately, did a little searching though. I'm curious, what is the purpose of splitting it 50/50 (not that it necessarily relates to answering your question and of course you don't have to explain if you don't want to - simply curious that's all)
Do you think this would work? Is that parcel data, and do you already use parcel fabric?

Maybe something here?
sorry, I didn't add text to that screen capture reply. Yes, you're correct the polys are not symmetrical; the splits may need to happen for just an unequal part of the poly. The selected poly in the screen capture is 6.00 acres. I need to manually split it into 2- 3.0 acre polys.
Sol,
Thinking about your symmetrical response made me understand what you mean. besides doing a symmetrical split, could I set the approx part of the original poly to split, like specifying the north end where I want a 2 ac split out of the 6-ac poly I show in my screen capture?
If doing it for just one polygon, I might use the measure tool to measure 2 acres of the north side, and maybe create feature edit tool and snap to vertices and create vertices where needed - does that make sense? Then use the edit tool for Splitting a Polygon.
If it were something you had to automate then it could take much longer and more complex math and scripting as Ian suggested - it could be very simple or very complex depending on your situation and scalability needed.
For your question - it doesn't matter what shape the split off piece is? Just the acreage?
Sol,
I've been trying a combination of the measure tool & create edit tool
w/ vertices depicted. Measurre tool snaps to the poly vertices, but does
not seem to offer more control on the size. I guess I don't understand
how you would use that combination to create an exact 2-ac chunk,
without a lot of trial and error.
