TASK DESCRIPTION
Given a set of points, it is frequently needed to calculate their "average" point - a weighted center of sorts. Simply creating a new point with AVG(longitude(point)), AVG(latitude(point)) may work in many places, but it could be grossly incorrect near anti-meridian.
this stackoverflow question provides a more accurate implementation, by transitioning each point's (lon, lat) into cartesian system (x,y,z), averaging on each coordinate, and converting back. If earth is assumed to be a sphere, the calculations are slightly simpler.
