distance()
distance(point1, point2)
point1
returning a point in either a geographic or cartesian coordinate system.
point2
returning a point in the same CRS as ‘point1’.
point() – WGS 84 2D
point({longitude | x, latitude | y [, crs][, srid]})
Returns a 2D point in the WGS 84 CRS corresponding to the given coordinate values.
point() – WGS 84 3D
point({longitude | x, latitude | y, height | z, [, crs][, srid]})
Returns a 3D point in the WGS 84 CRS corresponding to the given coordinate values.
point() – Cartesian 2D
point({x, y [, crs][, srid]})
Returns a 2D point in the Cartesian CRS corresponding to the given coordinate values.
point() – Cartesian 3D
point({x, y, z, [, crs][, srid]})
Returns a 3D point in the Cartesian CRS corresponding to the given coordinate values.
