POSC Specifications: Epicentre Version 3.0 | Logical Data Model |
A curvilinear 3D coordinate system based upon a geodetic datum. This left-handed coordinate system is defined by the orthogonal axes of latitude, longitude and ellipsoidal height. The latitude of a point is specified as an angle between the equatorial plane and a suitably chosen line thorough the point. The longitude of a point is specified as an angle between the local meridian of the point and the chosen reference meridian, measured in the equatorial plane. The height is the distance between a point and a vertical datum, such as the ellipsoidal surface associated with the geodetic datum.
- identifier (M, K, I: ndt_identifier) (C025)
- The name of the instance. Inherited from technical_reference.
- geodetic_datum (M: geodetic_datum(geographic_3d))
- This is the geodetic datum that this geographic coordinate system is based upon. This defines the surface upon which the coordinate values in this coordinate system are expressed. Each geographic_3d_coord_system must be based upon one geodetic_datum.
- geographic_2d_coord_system (M: geographic_2d_coord_system(geographic_3d_coord_system))
- This is the 2D geographic which was derived from this system by dropping the vertical axis. The standard identifiers for geographic systems should be loaded in the 2d system with the inverse of this relationship used to locate the related 3d system.

- ref_coordinate_sys_constraint (M, I: ref_coordinate_sys_constraint(coordinate_system)) (C112, C138)
- The type of the coordinate system. This type specifies the number, order and kinds of axes that must be defined for this coordinate system. For example, a coordinate system of geographical 2D must have two axes of latitude and longitude in order. Each geographic_3d_coord_system must be a kind of one ref_coordinate_sys_constraint. Inherited from coordinate_system.
