Generating polygons from line features where the lines aren't joined up

[SimonCrutchley]

Hi there, I'm looking for help on the above. I have a large number of features which have been delineated by contractors using lines to split them up, rather than by drawing polygons. Is there a simple way to create polygons from this data, without manually having to go in and trace the boundaries? I attach a sample set of the data.

Thanks

Likely you'll never get a 100% reliable solution here given the inputs are human generated.

Take a look at the "Extend Line" tool, which you can specify a distance and the tool will continue the existing lines to the nearest intersecting feature. Once you've run that then "feature to polygon" is your friend.

I would suggest trial an error of the individual processes manually first and when you happen upon a happy set of parameters then perhaps string them together with model builder or python.

You can also make polygons from lines in an edit session.

Awesome. Thanks. It hasn't found them all, and will need a bit of editing, but overall it will save a lot of time.

Thanks
