Whipped up quickly, so it needs optimization, refactoring, cleaning up, and possibly a complete rewrite from scratch.

It's based on using shapely

I'll try to upload the editor based on @geoman-io/leaflet-geoman-free when I get some free time.

In short:

  • I created a new class called polygon_zone that inherits from zone.
  • I added an attribute named points.
  • If the zone has points, then it’s a polygon_zone otherwise I use the old class, so I don’t have issues with backward compatibility.
  • I determine the center of the zone and its area.
  • In the _init_.py file, in the in_zone method, I check if the instance has the points attribute. If it does, I check if the tracker’s point is within the polygon using polygon.contains(point). This is on lines 97 to 104.
  • Otherwise, I check if the point is within the radius, like for normal zone.
