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 document 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).
ISO draws attention to the possibility that the implementation of this document may involve the use
of (a) patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed
patent rights in respect thereof. As of the date of publication of this document, ISO had not received
notice of (a) patent(s) which may be required to implement this document. However, implementers are
cautioned that this may not represent the latest information, which may be obtained from the patent
database available at www.iso.org/patents. ISO shall not be held responsible for identifying any or all
such patent rights.
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,
in collaboration with the Open Geospatial Consortium (OGC).
Any feedback or questions on this document should be directed to the user’s national standards body. A

AMENDMENT 1
3.1.13
Replace definition with:
3.1.13
datum ensemble
group of multiple realizations of the same terrestrial or vertical reference system that, for approximate
spatial referencing purposes, are not significantly different
EXAMPLE “WGS 84” as an undifferentiated group of realizations including WGS 84 (TRANSIT), WGS 84
(G730), WGS 84 (G873), WGS 84 (G1150), WGS 84 (G1674) and WGS 84 (G1762). At the surface of the Earth these
have changed on average by 0.7 m between the TRANSIT and G730 realizations, a further 0.2 m between G730
and G873, 0.06 m between G873 and G1150, 0.2 m between G1150 and G1674 and 0.02 m between G1674 and
G1762.
Note 1 to entry: Datasets referenced to the different realizations within a datum ensemble may be merged
without coordinate transformation.
Note 2 to entry: ‘Approximate’ is for users to define but typically is in the order of under 1 decimetre but may be
up to 2 metres.

3.1.15
Replace "[SOURCE: ISO 19111:2019, 3.1.9]" by "[SOURCE: ISO 19111:2019, 3.1.19]"

3.1.25
Replace definition with:
3.1.25
geodetic coordinate reference system
two- or three-dimensional coordinate reference system based on a geodetic datum reference frame and
having either a three-dimensional Cartesian or an ellipsoidal or a spherical coordinate system
Note 1 to entry: In this document a coordinate reference system based on a geodetic reference frame and having
an ellipsoidal coordinate system is geographic.

ISO 19162:2019/Amd.1:2023(E)
3.1.45
Replace definition with:
3.1.45
spherical coordinate system
two- or three-dimensional coordinate system in Euclidean space in which position is specified by two
angular coordinates and (in the three-dimensional case) one distance coordinate
Note 1 to entry: Not to be confused with an ellipsoidal coordinate system based on an ellipsoid ‘degenerated’ into
a sphere.
