Returns the spherical distance between two geometries (point or multipoint) on a sphere with the optional radiusr(default is the Earth radius ifris not specified), or NULL if not given valid inputs. Example set@zenica=ST_GeomFromText('POINT(17.907743 44.203438)');set@sarajevo=ST_GeomFromText...
For any two points on a sphere, the haversine of the central angle between them is given by where haversin is the haversine function: d is the distance between the two points (along a great circle of the sphere; see spherical distance), r is the radius of the sphere, : latitude of ...
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...
Since this is the "default" space in which we do almost every geometrical operation, and it's the one we have set for the calculator to operate on. Let's dive a bit deeper into Euclidean space, what is it, what properties does it have and why is it so important? The distance ...

For example, there are an infinite number of paths between two points on a sphere but, in general, only a single shortest path. The shortest distance between two points is the length of a so-called geodesic between the points. In the case of the sphere, the geodesic is a segment of a...
This paper describes a numerical simulation of bow shock formation ahead of a sphere at steady supersonic flow in the Mach number range of 1.025–1.20. Turbulent viscous flow results are presented using the Spalart–Allmaras turbulence model. The purpose of this study is to determine the shock ...
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. Environment settings Geoprocessing environment settings for global functions...
