A simple spatial representation of a position within an earth model. This may wholly represent the position or be part of the position.

description (O, I: ndt_comment)

A textual description of the earth model object. Inherited from earth_model_object.


identifier (O, I: ndt_name)

The local label used to identify an earth model object. Inherited from earth_model_object.


binset (O, I: binset(position_in_earth_model))

Defines the binset which is implied by the grid used in the geometry specification. The grid of the binset is defined using "bin line index" and/or "bin point index" values. The binset has properties which locate the grid in 2D space. Each earth_position_simple may use grid from one binset. Inherited from position_in_earth_model.


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_position_simple 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_position_simple may datum for ranking one or more object_ranking. Inherited from object_of_interest.


geologic_feature (O, I: geologic_feature(position_in_earth_model))

The geologic feature being represented by this position in the earth subsurface. Each earth_position_simple may represent one geologic_feature. Inherited from position_in_earth_model.


geologic_process (O, I: SET[0:?] geologic_process(position_in_earth_model))

Indicates a geologic process which is positioned by this location. Each earth_position_simple may locate one or more geologic_process. Inherited from position_in_earth_model.


geoscience_interpretation (O, I: geoscience_interpretation(earth_model_object))

The activity which created this object. Each earth_position_simple may result of one geoscience_interpretation. Inherited from earth_model_object.


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

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


identifying_whole (O: earth_position_composite(identify_part))

Specifies the composite spatial object to which this one belongs. Each earth_position_simple may identified by one earth_position_composite.


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


position_uncertainty_classification (I, V: SET[0:?] position_uncertainty_classification(earth_model_object))

Defines the set of classifications of this position with respect to its degree of uncertainty. Each earth_position_simple may be classified by one or more position_uncertainty_classification. Inherited from earth_model_object.


rock_feature_part (O, I: rock_feature_part(earth_model_object)) (1226)

This points to the rock feature part that this earth model object is representing spatially. Each earth_position_simple may be located by one rock_feature_part. Inherited from earth_model_object.


seismic_geometry_set (O: seismic_geometry_set(earth_position_simple))

Defines the geometry set which partially identifies this geometrical interpretation. This will typically point to the "2D line". Each earth_position_simple may identified by one seismic_geometry_set.


synthetic_log_trace (O, I: synthetic_log_trace(position_in_earth_model))

Indicates a synthetic log trace which is positioned in the earth at this location. Each earth_position_simple may locate one synthetic_log_trace. Inherited from position_in_earth_model.


whole (I, V: SET[0:?] earth_position_composite(part))

Indicates various spatial composite locations which utilize this position as a component. Each earth_position_simple may part of one or more earth_position_composite. Inherited from position_in_earth_model.

Local rules:

Abstract supertype:
Each EARTH_POSITION_SIMPLE must be instantiated as one of its subtypes. These subtypes are: earth_position_edge, earth_position_face, earth_position_region, earth_position_ring, earth_position_shell, earth_position_vertex
Same Related Instance
Any instance of EARTH POSITION SIMPLE that is identified by an EARTH POSITION COMPOSITE must be part of that EARTH POSITION COMPOSITE.
Optional Relationship Set
Each instance may represent a geologic_feature or be identified by an identifying_whole.
Instance Value Constraint
If the instance partially identifies a seismic_geometry_set, then it must also be part of an identifying_whole.
Supertype path(s):
e_and_p_data > object_of_interest > technical_object > earth_model_object > position_in_earth_model > earth_position_simple.
