POSC Specifications: Epicentre Version 3.0 | Logical Data Model |
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.
- seismic_facility (M, K: geophysical_facility(seismic_facility_track))
- Defines the facility which is being tracked. Each seismic_facility_track must facility definition one geophysical_facility.
- seismic_geometry_set (M, K: seismic_geometry_set(seismic_facility_track))
- Defines the geometry set which defines the source event grid. Each seismic_facility_track must source event definition one seismic_geometry_set.
- description (O, I: ndt_comment) (C117)
- A remark or comment about the instance. Inherited from e_and_p_data.
- instance_create_date (O, I: ndt_date_tod) (C126)
- This is the date that this instance was created. This date is defined by the source if imported, or is the date the instance is created if a new instance. Inherited from e_and_p_data.
- instance_creator (O, I: ndt_identifier) (C126)
- This is the person, company or application that created this instance. This identifies the party responsible for loading this instance. Inherited from e_and_p_data.
- last_updated (O, I: ndt_date_tod) (C126)
- This is the date that this instance was last updated. This value should be updated when any part of this instance is altered (except for inverse relationships). Inherited from e_and_p_data.
- last_updated_by (O, I: ndt_identifier) (C126)
- This records the person or application making the update to this instance. Inherited from e_and_p_data.
- source (O, I: ndt_identifier) (C126)
- The provider of this instance, which is usually a data provider for imported/purchased data. If this instance is provided by POSC, then this attribute must be "POSC". Inherited from e_and_p_data.
- data_collection (I, V: SET[0:?] data_collection_content(collection_part)) (C020)
- Indicates the data collections that include this instance of E and P data. Each seismic_facility_track may be a member of one or more data_collection_content. Inherited from e_and_p_data.
- document_information_content (I, V: SET[0:?] document_information_content(e_and_p_data)) (C136)
- These are the document specification parts that include this data value and define its meaning within a document specification. Each use may define a different meaning, and many uses are allowed. Each seismic_facility_track may be included in one or more document_information_content. Inherited from e_and_p_data.
- graphical_element (I, V: SET[0:?] graphical_element(depicted_object))
- Specifies one or more graphical elements which are depicting this data item. Each seismic_facility_track may be depicted by one or more graphical_element. Inherited from e_and_p_data.
- pty_location_array (V: SET[0:?] pty_location_array(seismic_facility_track))
- 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. Each seismic_facility_track may have a property of one or more pty_location_array.
- pty_vertical_location_array (V: SET[0:?] pty_vertical_location_array(seismic_facility_track))
- 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. Each seismic_facility_track may have a property of one or more pty_vertical_location_array.
- pty_water_depth_array (V: SET[0:?] pty_water_depth_array(seismic_facility_track))
- 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. Each seismic_facility_track may have a property of one or more pty_water_depth_array.
