Public Methods

Method	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.

Method Details

AngularDistance() public static method

Computes an angular distance between two points on the unit sphere.

public static AngularDistance ( GeoPoint p1, GeoPoint p2 ) : double
p1	GeoPoint
p2	GeoPoint
return	double

GetConvexHull() public static method

Computes a convex hull of the specified points.

public static GetConvexHull ( IEnumerable points ) : IList
points	IEnumerable	Enumerator of coordinates for which convex hull should be computed
return	IList

GetPointsCentroid() public static method

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.

public static GetPointsCentroid ( IEnumerable points ) : GeoPoint
points	IEnumerable
return	GeoPoint
