Coordinates of an address point are the pair of coordinates (astronomical or geodetic) that allow to locate it In the space / on the Earth surface.

Geodetic coordinates, pair of spherical coordinates called latitude and longitude geodetic that specifies the location of a point P on the reference ellipsoid in the coordinate system defined by the axis of rotation of the ellipsoid, the plane of its equator and the contractually agreed meridian plane.

Geographical coordinates (ASTRONOMIC COORDINATES), the pair of spherical coordinates called latitude and longitude astronomical relative to the coordinate system defined by the axis of rotation of the Earth, the Earth's equator and the contractually agreed meridian plane.
