The amount of surface occupied by an object expressed in units of length squared.

earth_surface_feature (O, K: earth_surface_feature(pty_area))

Each pty_area may be a property of one earth_surface_feature.


fossil_taxon (O, K: fossil_taxon(pty_area))

Each pty_area may be a property of one fossil_taxon.


rock_material (O, K: rock_material(pty_area))

Each pty_area may be a property of one rock_material.


well_pad (O, K: well_pad(pty_area))

Each pty_area may be a property of one well_pad.


general_land_right (O, K: general_land_right(pty_area))

Each pty_area may be a property of one general_land_right.


face (O, K: face(pty_area))

Each pty_area may be a property of one face.


other_spatial_object (O, K, I: other_spatial_object(property))

Each pty_area may be a property of one other_spatial_object. Inherited from property.


hole (O, K: hole(pty_area))

Each pty_area may be a property of one hole.


activity (O, K, I: activity(process_data))

Defines the activity which created this instance. Each pty_area may be the result of one activity. Inherited from process_data.


data_value (M: ndt_area)

A value of area. Examples: 450 acres, 4.567 mm**2.


preferred_flag (O, I: ndt_boolean) (1047)

The flag is set to True if this instance of property is the preferred value in this data store of this type of property for the object which this property describes. Inherited from property.


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

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


process_data_item (I, V: SET[0:?] process_data_item(process_data))

Defines where this data was used by an activity. Each pty_area may be the value for one or more process_data_item. Inherited from process_data.

Local rules:

Uniqueness Constraint
earth_surface_feature, fossil_taxon, rock_material, well_pad, general_land_right, face, other_spatial_object, hole, activity
[I: property] Mandatory Relationship Set
Each PROPERTY must "be a property of" one object.
Supertype path(s):
process_data > property > pty_area.
e_and_p_data > property > pty_area.
