[FEATURE] Compute center of a polygon

[aarongerig]

It would be nice to have a method in the Polygon class, which computes and returns the center of all coordinates.

Is this something you would be interested in?

Hi,

that'd be a nice addition. The referenced algorithms are for planar polygons only. We have to find something that works on the surface of an ellipsoid. Lets see if we find the time for research and implementation :-)

WDYT about this one, @mjaschen? https://bell0bytes.eu/centroid-convex/
