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 on 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 the following

This document was prepared by Technical Committee ISO/TC 211, Geographic information/Geomatics.
This second edition cancels and replaces the first edition (ISO 19112:2003), which has been technically
revised.
The main changes compared to the first edition are as follows:
— revision of the conceptual schema to meet current standards and harmonise with other ISO/TC 211
standards;
— introduction of the class LocationClass to replace the class SI_LocationType;
— introduction of the class Location to replace the class SI_LocationInstance;
— introduction of the class SpatialReferenceSystemUsingGeographicIdentifiers to replace the class
SI_SpatialReferenceSystemUsingGeographicIdentifiers;
— introduction of the class Gazetteer to replace the class SI_Gazetteer;
— introduction of the class GeographicIdentifier;
— recognition that a gazetteer is a sub-type of Register as defined in ISO 19135-1, and that Location
Class is an ItemClass and Location a RegisterItem in that context;
— changes to package identifiers.
The changes are elaborated in Annex D.
Any feedback or questions on this document should be directed to the user’s national standards body. A

Introduction
Geographic information contains spatial references that relate information represented in data or text
to positions in geographic space.
Spatial references fall into two categories:
a) those using coordinates;
b) those using geographic identifiers.
This document deals only with spatial referencing by geographic identifiers. This type of spatial
reference is sometimes called “indirect”. Spatial referencing by coordinates is the subject of ISO 19111.
Spatial reference systems using geographic identifiers are based not explicitly on coordinates but on a
relationship with a location defined by a geographic feature or features. The relationship of the position
to the feature may be as follows:
— containment, where the position is within the geographic feature, for example in a country;
— local measurements, where the position is defined relative to a fixed point or points in the geographic
feature or features, for example at a given distance along a street from a junction with another
street. This aspect, known as linear referencing, is the subject of ISO 19148;
— loosely related, where the position has a fuzzy relationship with the geographic feature or features,
for example adjacent to a building or between two buildings.
The purpose of this document is to specify ways to define and describe systems of spatial references
using geographic identifiers. It only covers the definition and recording of the referencing feature, and
does not consider the forms of the relationship of the position relative to that feature.
A spatial reference system using geographic identifiers is a collection of Location classes of different
sub-types, while a gazetteer is a collection of Location instances (of one or more Location sub-types).
A common form of spatial referencing system using geographic identifiers is addressing. This is the
subject of ISO 19160-1.

INTERNATIONAL STANDARD ISO 19112:2019(E)
Geographic information — Spatial referencing by
geographic identifiers
1 Scope
This document defines the conceptual schema for spatial references based on geographic identifiers.
It establishes a general model for spatial referencing using geographic identifiers and defines the
components of a spatial reference system. It also specifies a conceptual scheme for a gazetteer.
Spatial referencing by coordinates is addressed in ISO 19111. However, a mechanism for recording
complementary coordinate references is included in this document.
This document enables producers of data to define spatial reference systems using geographic
identifiers and assists users in understanding the spatial references used in datasets. It enables
gazetteers to be constructed in a consistent manner and supports the development of other standards
in the field of geographic information.
This document is applicable to digital geographic data, and its principles may be extended to other
forms of geographic data such as maps, charts and textual documents.
2 Normative references
