Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to the
World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see www .iso
.org/iso/foreword .html.
This document was prepared by Technical Committee ISO/TC 211, Geographic information/Geomatics.
This first edition cancels and replaces ISO/TS 19127:2005, which has been technically revised.
The main changes compared to the previous edition are as follows:
— the title has changed from Geodetic codes and parameters to Geodetic register;
— the normative references are updated to reflect revisions, ISO 19115-1:2014 and ISO 19162:2015 are
added and ISO 19112 removed;
— the Management of a register of geodetic codes and parameters clause is removed;
— the Management of a register of geodetic codes and parameters clause is replaced by Geodetic
register management roles and responsibilities and Geodetic register management rules and
procedures clauses with the latter referencing ISO 19135-1:2015 in specifying modified, unmodified
and additional requirements;
— a Terms of reference of the control body for the ISO 19127 geodetic register clause is added;
— the Content of a register of geodetic codes and parameters clause is replaced by a Geodetic register
content requirements clause which references ISO 19111:2007 and ISO 19135-1:2015 in specifying
modified, unmodified and additional content;
— an ISO 19127 geodetic registry data export clause is added;
— Annex A (normative) is extended and updated to reflect revisions;
— Annex B (normative) is extended and updated to reflect the required elements within the geodetic
register;
— Annex C (informative) is updated to reflect revisions and extended to include extents;
— Annex D (informative) Metadata and Annex E (informative) Requirements list are added.

In accordance with the ISO/IEC Directives, Part 2, 2018, Rules for the structure and drafting of
International Standards, in International Standards the decimal sign is a comma on the line. However,
the General Conference on Weights and Measures (Conférence Générale des Poids et Mesures) at its
meeting in 2003 passed unanimously the following resolution:
“The decimal marker shall be either a point on the line or a comma on the line.”
In practice, the choice between these alternatives depends on customary use in the language concerned.
In the technical areas of geodesy and geographic information it is customary for the decimal point
always to be used, for all languages. That practice is used throughout this document.
Any feedback or questions on this document should be directed to the user’s national standards body. A
complete listing of these bodies can be found at www .iso .org/members .html.
Introduction
This document specifically governs procedures for the ISO 19127 geodetic register, but may have
applicability to similar national and international registers of geodetic information.
The ISO 19127 geodetic register and the ISO 19127 geodetic registry are referred to as the ISO geodetic
register and ISO geodetic registry, respectively, throughout this document.
ISO 19135-1:2015 specifies procedures for the registration of items of geographic information. ISO/
IEC JTC 1 defines registration as the assignment of an unambiguous name to an object in a way that
makes the object available to interested parties. ISO 19135-1:2015 has changed the definition of
registration to the assignment of linguistically independent identifiers, rather than names, to items
of geographic information. ISO 19135-1:2015, Annex C is applicable to ISO/TC 211 registers. The
ISO geodetic register is one such register.
ISO 19111:2007 describes elements necessary to define single and compound coordinate reference
systems so that coordinates for positions on or near the Earth’s surface can be unambiguously
referenced. ISO 19111:2007 also describes elements to define coordinate operations that change
coordinate values from one coordinate reference system to coordinate values based on another
coordinate reference system.
This document describes how the procedures specified in the core schema within ISO 19135-1:2015 are
to be applied to the ISO geodetic register of elements applicable to spatial referencing by coordinates
in accordance with ISO 19111:2007. Some elements that are optional in ISO 19111:2007 become
mandatory in this document to provide guidance on applicability and appropriate use.
Annex A, which is normative, provides four tests for conformance to this document.
Annex B, which is normative, provides tables that specify information for elements to be included in the
ISO geodetic register.
Annex C, which is informative, provides best practices for the ISO geodetic register content.
Annex D, which is informative, provides the metadata for the ISO geodetic register.
Annex E, which is informative, provides a summary of the conformance requirements that are found in
the text body of this document.

3.1
retirement
declaration that a register item is no longer suitable for use in the production of new data
Note 1 to entry: The status of the retired item changes from “valid” to “retired”. A retired item is kept in the
register to support the interpretation of data produced before its retirement and has not been superseded by
another item.
Note 2 to entry: In the geodetic register retired items are not necessarily invalid.
[SOURCE: ISO 19135-1:2015, 4.1.14, modified — Note 2 to entry has been added.]
3.2
supersession
declaration that a register item has been retired and replaced by one or more new items
Note 1 to entry: The status of the replaced item changes from “valid” to “superseded”.
Note 2 to entry: In the geodetic register superseded items are not necessarily invalid.
[SOURCE: ISO 19135-1:2015, 4.1.17, modified — Note 2 to entry has been added.]
