I'm trying to make polygons from a line track recorded by a GPS in order to get a rough area that the line was made in. I would like to keep most of the outer edge outline except where it is within a certain distance from itself.
Minimum bounding with the convex hull is simply too aggressive, I'm looking for something more like "delete holes" except it needs to work with holes that are open-ended. I start with a long and skinny buffered track.
I then use "delete holes" to fill in the gaps.
Then this is what I would like the end product to look like, which I was only able to do by manually deleting some points and rearranging others.
This is what it looks like using a convex hull but I would like to keep those top and bottom curves, as well as slight indents on the sides.
I have tried using smooth polygons as well but the curvatures are way too small to make any difference.
