Méthode Description
AngularDistance ( GeoPoint p1, GeoPoint p2 ) : double

Computes an angular distance between two points on the unit sphere.
GetConvexHull ( IEnumerable points ) : IList

Computes a convex hull of the specified points.
GetPointsCentroid ( IEnumerable points ) : GeoPoint

Calculates the center of mass of points. Calculated as the point on the surface of the ellipsoid, which "points to" a vector, which is the sum of the vectors coming from the center of the ellipsoid to each of the points.

Masses of points are set equal.
