Distance accuracy

Polycircle uses Python’s geographiclib for distance calculations.

Method Accuracy
Simple trigonometry Dozens of meters
geographiclib 10^-4 meters

The distance was measured by geopy.

How many vertices?

Raising the number of vertices makes the polygon illusion more compelling. On the other side, too many vertices make the KML file larger and Google Earth slower.

In my opinion, 36 edges are the right balance between appearances and file size.
