source_coordinate_system                  MU      coordinate_system

                                          This designates the coordinate system which is
                                          the source for the coordinate transformation.
                                          When transforming from a geographic to a projected
                                          coordinate system, this points to the geographic
                                          system. 

target_coordinate_system                  MU      coordinate_system

                                          This designates the coordinate system which is
                                          the target for the coordinate transformation.
                                          When transforming from a geographic to a projected
                                          coordinate system, this points to the projected
                                          system. 

face                                              face

                                          This describes a face used as a screen, as when
                                          a three dimensional object is projected into two
                                          dimensions. 

edge                                              edge

                                          The describes the use of an edge as a screen,
                                          as when a two or three dimensional object is projected
                                          onto a line. 

coordinate_transformation                 MU      coordinate_transformation

                                          This defines the coordinate transformation which
                                          was used to transform the source coordinate system
                                          into the target coordinate system. 

coordinate_transformation_activity        V       set[0 .. N] of (coordinate_transformation_activity)

                                          These are the activities that record the application
                                          of a coordinate transformation to the source and
                                          target coordinate systems.
