An identified method and set of parameter values used to convert from one coordinate system to another coordinate system.

identifier (M, K: ndt_name)

The identifier of the coordinate transformation.


coordinate_transformation_method (M: coordinate_transformation_method(coordinate_transformation))

This is the method used to define the coordinate transformation. The method describes the parameters to be used and the manner in which they are used. Each coordinate_transformation must be defined by one coordinate_transformation_method.


source (M, I: ref_source)

The provider of this instance of reference information. If this instance is provided by POSC, then this attribute must be "POSC". Each coordinate_transformation must provided by one ref_source. Inherited from reference_behavior.


description (O: ndt_comment)

A remark about the use of the coordinate transformation.


status (O, I: ndt_instance_status) (0644)

The status of this instance in the version of Epicentre running in a data store. This is an enumerated datatype for which the following are the possible values: current, provisional, deprecated. Current - use without restriction. Provisional - use with caution, this value is for comment and may not appear in future releases of Epicentre. Deprecated - avoid use if possible, it is planned to remove this value in the next major release of Epicentre. Inherited from reference_behavior.


applied_coordinate_transformation (V: SET[0:?] applied_coordinate_transformation(coordinate_transformation))

This describes the instances where this coordinate transformation was used to transform one coordinate system into another. Each coordinate_transformation may be utilized by one or more applied_coordinate_transformation.


coordinate_transformation_aoi (O: SET[0:?] earth_surface_feature(coordinate_transformation))

These are the areas of the surface of the Earth that are defined as appropriate to use this coordinate transformation. Each coordinate_transformation may be defined for use within one or more earth_surface_feature.


coordinate_transformation_value (V: SET[0:?] coordinate_transformation_value(coordinate_transformation))

These are the values of the coordinate transformation parameters that are defined for the coordinate transformation method that defines this coordinate transformation. Each coordinate_transformation may utilize one or more coordinate_transformation_value.


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

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


ref_coordinate_transform_constraint (O: ref_coordinate_transform_constraint)

A constraint which defines the types of coordinate systems that must be used as the basis of and result of the application of a coordinate transformation. This constraint is implemented by an applied coordinate transformation.


source_reference (O, I: ref_source_reference)

The reference used by source to provide the standard instance, such as Petroleum Industry Data Dictionary (PIDD), Websters Ninth New Collegiate Dictionary, etc. Each coordinate_transformation may documented by one ref_source_reference. Inherited from reference_behavior.


version (O, I: ref_epicentre_version) (0644)

Describes the version of Epicentre when this status was assigned to this instance of reference behavior Each coordinate_transformation may version one ref_epicentre_version. Inherited from reference_behavior.
