Discussion
This method measures the distance between the location in the current object and the value in the location parameter. The distance is calculated by tracing a line between the two points that follows the curvature of the Earth, and measuring the length of the resulting arc. The arc is a smooth curve that does not take into account altitude changes between the two locations.
