A simple graphical element representing a surface area of a depiction.

identifier (M, I: ndt_name)

The identifying label assigned to a graphical element. Inherited from graphical_element.


document_specification (M, I: document_specification(graphical_composition))

Specifies the document specification in which this graphic element is defined. Each area_element must be part of one document_specification. Inherited from graphical_element.


bounding_ring (O: SET[0:?] ring_element)

Specifies the edge or set of edges which delimit the area element. Each area_element may be bounded by one or more ring_element.


cell (O, I: cell(cell_shape))

Indicates the usage of a graphical element as the pattern of a cell. Each area_element may specify the shape of one cell. Inherited from graphical_element.


data_collection (I, V: SET[0:?] data_collection(collection_content))

Indicates the data collections that include this instance of E and P data. Each area_element may be a member of one or more data_collection. Inherited from e_and_p_data.


datum_for_ranking (I, V: SET[0:?] object_ranking(base_object))

Indicates that an object is being used as a basis for comparison with another object. Each area_element may datum for ranking one or more object_ranking. Inherited from object_of_interest.


depicted_object (O, I: e_and_p_data(graphical_element))

Indicates the data item or information which is being graphically depicted. Each area_element may depict one e_and_p_data. Inherited from graphical_element.


earth_model (I, V: SET[0:?] earth_model(spatial_object))

Indicates various earth models which include this spatial representation. Each area_element may be part of one or more earth_model. Inherited from spatial_object.


graphical_element (I, V: SET[0:?] graphical_element(depicted_object))

Specifies one or more graphical elements which are depicting this data item. Each area_element may be depicted by one or more graphical_element. Inherited from e_and_p_data.


graphical_element_component (O, I: composite_graphical_element(composition))

Indicates the usage of this graphical element as a part of a composite graphical element. Each area_element may be a component of one composite_graphical_element. Inherited from graphical_element.


intersection_role (I, V: SET[0:?] space_time_operation(intersecting_object))

Indicates a space/time operation for which the object is involved as an intersecting agent. For projection, this is the screen on which an object is being projected. For proximity, this is the magnet object. Each area_element may be the intersecting object for one or more space_time_operation. Inherited from topological_object.


object_of_ranking (I, V: SET[0:?] object_ranking(ranked_object))

Indicates that an object is being classified in a rank order based on its characteristics. Each area_element may object of ranking one or more object_ranking. Inherited from object_of_interest.


other_composite_spatial_object (I, V: SET[0:?] other_composite_spatial_object(composite_object))

Defines the set of composite spatial objects of which this spatial object is a component. Each area_element may be a component of one or more other_composite_spatial_object. Inherited from spatial_object.


primary_role (I, V: SET[0:?] space_time_operation(primary_object))

Indicates a space/time operation for which the object is involved as a primary agent. For degeneration, this object is being degenerated. For projection, this object is being projected onto another object. For proximity, this is the container object. Each area_element may be the primary object for one or more space_time_operation. Inherited from topological_object.


primary_topological_relationship (I, V: SET[0:?] topological_relationship(primary_topological_object))

Indicates a topological relationship in which the topologic object has the role of primary agent. For an object intersection type of "inside" this is the containing role (e.g., if a city is inside a county then the county would be the primary agent). For all other object intersection types the roles are symmetrical and both relationships must be searched for a particular object. For example, if a wellbore and a formation overlap then either could be chosen as the primary agent with the other chosen as the secondary agent. Each area_element may be primarily involved in one or more topological_relationship. Inherited from topological_object.


pty_area (I, V: SET[0:?] pty_area(face))

Each area_element may have a property of one or more pty_area. Inherited from face.


pty_geometry_2d_face (I, V: SET[0:?] pty_geometry_2d_face(face))

Each area_element may have a property of one or more pty_geometry_2d_face. Inherited from face.


pty_geometry_3d_face (I, V: SET[0:?] pty_geometry_3d_face(face))

Each area_element may have a property of one or more pty_geometry_3d_face. Inherited from face.


secondary_topological_relationship (I, V: SET[0:?] topological_relationship(secondary_topological_object))

Indicates a topological relationship in which the object is in the role of secondary agent. For an object intersection type of "inside" this is the contained role (e.g., if a well is inside a field then the well would be the secondary agent). For all other object intersection types the roles are symmetrical and both relationships must be searched for a particular object. For example, if a wellbore and a formation overlap then either could be chosen as the secondary agent with the other chosen as the primary agent. Each area_element may be involved in one or more topological_relationship. Inherited from topological_object.


shell (O, I: SET[0:?] shell(face))

Defines the shells of which this face is a component. Each area_element may be a component of one or more shell. Inherited from face.


source_space_time_operation (I, V: BAG[0:1] space_time_operation(resulting_object))

Indicates the space/time operation from which a topological object was the result. For addition, this is the union of two objects. For degeneration, this is the degenerate object. Each area_element may be the result of one space_time_operation. Inherited from topological_object.
