Entity seismic_facility_track

• Identifies a subset of the path of the facility. The associated pty seismic facility location will define the locations at "the time of" source events defined within the context of the seismic geometry set. This should not be used to track source facilities or receiver facilities because these facilities have location attributes in seismic geometry set.

From association:
   data_collection                        IV      set[0 .. N] of (data_collection)

                                          Indicates the data collections that include this
                                          instance of E and P data. 

   graphical_element                      IV      set[0 .. N] of (graphical_element)

                                          Specifies one or more graphical elements which
                                          are depicting this data item. 


seismic_facility                          MU      seismic_facility

                                          Defines the facility which is being tracked. 

seismic_geometry_set                      MU      seismic_geometry_set

                                          Defines the geometry set which defines the source
                                          event grid. 

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

                                          May have a property of pty element value. The
                                          grid must match the grid used by source event
                                          uid in the associated seismic geometry set. This
                                          allows, for example, the air pressure of a source
                                          facility to be defined for each source event.

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

                                          May have a property of pty location array. The
                                          location of the facility at the time of each source
                                          event. The grid must match the grid used by source
                                          event uid in the associated seismic geometry set.

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

                                          May have a property of pty water depth array.
                                          Defines the water depth at the facility for each
                                          source event. The grid must be the same as was
                                          defined by attribute source event uid in the associated
                                          seismic geometry set. 

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

                                          May have a property of pty vertical location array.
                                          The grid must match the grid used by source event
                                          uid in the associated seismic geometry set.
