描述

¥Description

Takes a 点 and calculates the location of a destination point given a distance in degrees, radians, miles, or kilometers;方位角（以度为单位）。This uses the 半正矢公式 to account for global curvature.

¥Takes a Point and calculates the location of a destination point given a distance in degrees, radians, miles, or kilometers; and bearing in degrees. This uses the Haversine formula to account for global curvature.
