Methods

distance(Point from, Point to) → double?
Computes the distance between from and to positions. Returns the great-circle distance using 'haversine' formula. Point.altitude values are ignored. from and to positions must be geography-based, i.e. their latitude and longitude are both set; otherwise null is returned.
override
measure(Shape shape) → double?
Computes the length of a line or polygon by adding up distances between consecutive Points making it up. Returns null if distance return null for any two consecutive Points.
