double[] nearestPointSegment (double[] a, double[] b, double[] c) { double[] t= nearestPointGreatCircle(a,b,c); if (onSegment(a,b,t)) return t; return (distance(a,c) < distance(b,c)) ? a : c; } How to calculate distance from a point to a line segment, on a sphere?
ST_DISTANCE_SPHERE(g1,g2,[r]) DescriptionReturns the spherical distance between two geometries (point or multipoint) on a sphere with the optional radius r (default is the Earth radius if r is not specified), or NULL if not given valid inputs....
function, which is another way to measure distances on a sphere: => select haversine(122.55688, 45.513746, 122.396357, 47.648845); haversine --- 79.9258188445352 That distance is miles, which is almost exactly equivalent to the 128.8km figure from earth...
Relying on the reference ellipsoid associated with a map projection structure (mstruct) Whenever you are doing a computation that involves a reference sphere or ellipsoid, make sure that the units of length you are using are the same units used to define the radius of the sphere or semimajor...

Note: One use for a geodesic line is when you want to determine the shortest distance between two cities for an airplane's flight path. This is also known as a great circle line if based on a sphere rather than an ellipsoid.
In the first step (the visualization of the shape spaces simulating uniform distribution of triangles), Rohlf21 demonstrates that Kendall’s shape space corresponds to the surface of a sphere, as already shown analytically by Kendall12. In the case of triangles, the linear tangent space is a pl...
