A spatial model of the earth surface and subsurface, containing a network of earth model objects, such as rock and fluid bodies.

identifier (M, K: ndt_name)

The label by which an earth model is identified.


geoscience_interpretation (O, K: geoscience_interpretation(earth_model))

The activity which created this model. Each earth_model may be created by one geoscience_interpretation.


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

Indicates the data collections that include this instance of E and P data. Each earth_model 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 earth_model may datum for ranking one or more object_ranking. Inherited from object_of_interest.


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

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


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 earth_model may object of ranking one or more object_ranking. Inherited from object_of_interest.


spatial_object (O: SET[0:?] spatial_object(earth_model))

Indicates the population of spatial representations which comprise this earth model. Each earth_model may contain one or more spatial_object.
