An intersection entity that describes the application of a coordinate transformation between two coordinate systems.

app_cord_trfm_s (PK, M: CHAR VARYING(19))

Surrogate key of the table.


coordinate_trfm_id (FNK, M: CHAR VARYING(40))

applied_coordinate_transformation.coordinate_transformation
This defines the coordinate transformation which was used to transform the source coordinate system into the target coordinate system.
Defines a foreign key to table coordinate_trfm.


source (FNK, M: CHAR VARYING(40))

reference_behavior.source
The provider of this instance of reference information. If this instance is provided by POSC, then this attribute must be "POSC".
Defines a foreign key to table r_source.


source_cord_sys (FNK, M: CHAR VARYING(40))

applied_coordinate_transformation.source_coordinate_system
This designates the coordinate system which is the source for the coordinate transformation. When transforming from a geographic to a projected coordinate system, this points to the geographic system.
Defines a foreign key to table coordinate_sys.


target_cord_sys (FNK, M: CHAR VARYING(40))

applied_coordinate_transformation.target_coordinate_system
This designates the coordinate system which is the target for the coordinate transformation. When transforming from a geographic to a projected coordinate system, this points to the projected system.
Defines a foreign key to table coordinate_sys.


description (O: CHAR VARYING(2000))

applied_coordinate_transformation.description
A description of the applied coordinate transformation


status (O: CHAR VARYING(11))

reference_behavior.status
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.


edge_s (FSK, O: CHAR VARYING(19))
edge_t (O: CHAR VARYING(16))

applied_coordinate_transformation.edge
The describes the use of an edge as a screen, as when a two or three dimensional object is projected onto a line.
edge_s: Implements a foreign key to a row in one of the tables projected from entity edge depending on the value of the next column (See below).
edge_t: Defines the name of the referenced table. Possible values are defined in @edge.


face_s (FSK, O: CHAR VARYING(19))
face_t (O: CHAR VARYING(16))

applied_coordinate_transformation.face
This describes a face used as a screen, as when a three dimensional object is projected into two dimensions.
face_s: Implements a foreign key to a row in one of the tables projected from entity face depending on the value of the next column (See below).
face_t: Defines the name of the referenced table. Possible values are defined in @face.


source_reference_s (FSK, O: CHAR VARYING(19))

reference_behavior.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.
Defines a foreign key to table r_source_ref.


version (FNK, O: CHAR VARYING(40))

reference_behavior.version
Describes the version of Epicentre when this status was assigned to this instance of reference behavior
Defines a foreign key to table r_epcnt_version.
