The specification of a set of axes that defines an indexing system in one or more dimensions.

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

Surrogate key of the table.


coordinate_sys_id (M: CHAR VARYING(40))

coordinate_system.identifier
The identifier of the coordinate system.


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

coordinate_system.ref_coordinate_system_constraint

Defines a foreign key to table r_cord_sys_cstr.


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

reference_behavior.source

Defines a foreign key to table r_source.


entity_type_nm (M: CHAR VARYING(40))

Column that contains the name of the entity that this row is an instance of in case a table represents multiple entities. Possible values are: geocentric_coordinate_system, geographic_coordinate_system, local_spatial_coordinate_system, nonspatial_coordinate_system, projected_coordinate_system.


description (O: CHAR VARYING(2000))

coordinate_system.description
A remark concerning the coordinate system.


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.


geodetic_datum_id (FNK, O: CHAR VARYING(80))

geocentric_coordinate_system.geodetic_datum
This describes the geodetic datum that is the basis of this geocentric coordinate system.
geographic_coordinate_system.geodetic_datum
This is the geodetic datum that this geographic coordinate system is based upon. This defines the surface upon which the coordinate values in this coordinate system are expressed.
Defines a foreign key to table geodetic_datum.


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

geographic_coordinate_system.prime_meridian
This is the prime meridian for the geographic coordinate system.
Defines a foreign key to table prime_meridian.


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

coordinate_system.ref_axis_orientation
The orientation of the axis with respect to previously defined axes in the coordinate system. Each coordinate system may be either "right-handed" or "left-handed".
Defines a foreign key to table r_axis_ornt.


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

local_spatial_coordinate_system.ref_display_orientation
This describes the default location of the origin that may be used when displaying information using this local coordinate system.
Defines a foreign key to table r_display_ornt.


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

projected_coordinate_system.ref_map_projection
The type of map projection algorithm that characterizes the projection coordinate system.
Defines a foreign key to table r_map_proj.


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

coordinate_system.ref_naming_system
The naming system in which identifier type and structure is defined.
Defines a foreign key to table r_naming_system.


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.


vertex_s (FSK, O: CHAR VARYING(19))
vertex_t (O: CHAR VARYING(16))

coordinate_system.vertex
This is the origin of the coordinate system, where all axes of the coordinate system intersect.
vertex_s: Implements a foreign key to a row in one of the tables projected from entity vertex depending on the value of the next column (See below).
vertex_t: Defines the name of the referenced table. Possible values are defined in @vertex.
