 Group Distance Calculations

The group "Distance Calculations" contains functions for the calculation of the distance between two coordinates. Other functions calculate the coordinate of a target point based on the parameters start point coordinate, bearing and distance. According to the formulas of Vincenty the Direct Position Computation and the Inverse Position Computation will be done.

Characteristics of the function group

 • Distance between coordinates on the ellipsoid
 • Distance between coordinates on the sphere
 • Distance between UTM coordinates
 • Destination point from start point, bearing, distance on ellipsoid
 • Destination  point from start point, bearing, distance on sphere
 • UTM destination point from UTM start point, bearing and distance
 • Vincenty's Direct and Inverse Position Computation
 o Distance, forward bearing, backward bearing
