The need is to be able to mark if the interior rings in each polygon are passable or not.

Each interior ring will have an (integer) ID. We will use the M attribute to store the shape id.

Here we would include a reference to a dictionary linking these IDs with:

  • A name for the ring (e.g., "Pond")
  • Whether the ring is passable or not.
