ST_Distance_Sphere(g1g2 [, radius])

Returns the mimimum spherical distance between two points and/or multipoints on a sphere, in meters, or NULL if any geometry argument is NULL or empty.

Calculations use a spherical earth and a configurable radius. The optional radius argument should be given in meters. If omitted, the default radius is 6,370,986 meters. An ER_WRONG_ARGUMENTS error occurs if the radius argument is present but not positive.

The geometry arguments should consist of points that specify (longitude, latitude) coordinate values:

  • Longitude and latitude are the first and second coordinates of the point, respectively.

  • Both coordinates are in degrees.

  • Longitude values must be in the range (-180, 180]. Positive values are east of the prime meridian.

  • Latitude values must be in the range [-90, 90]. Positive values are north of the equator.

Supported argument combinations are (PointPoint), (PointMultiPoint), and (MultiPointPoint). An ER_GIS_UNSUPPORTED_ARGUMENT error occurs for other combinations.

If any geometry argument is not a syntactically well-formed geometry byte string, an ER_GIS_INVALID_DATA error occurs.
