Geographic information - Spatial referencing by geographic identifiers (ISO 19112:2019)

This Standard 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.

Information géographique - Système de références spatiales par identificateurs géographiques (ISO 19112:2019)

Le présent document définit le schéma conceptuel d'un système de références spatiales basé sur des identificateurs géographiques. Il établit un modèle général du système de références spatiales utilisant des identificateurs géographiques et définit les composants de ce système. Il spécifie également le schéma conceptuel d'un répertoire géographique.
Le système de références spatiales par coordonnées est traité dans l'ISO 19111. Un mécanisme destiné à l'enregistrement de coordonnées de référence complémentaires est toutefois inclus dans le présent document.
Le présent document permet aux producteurs de données de définir des systèmes de références spatiales utilisant des identificateurs géographiques et aide les utilisateurs à comprendre les références spatiales utilisées dans les ensembles de données. Il permet de construire des répertoires géographiques de manière cohérente et soutient le développement d'autres normes dans le domaine de l'information géographique.
Le présent document est applicable aux données géographiques numériques et ses principes peuvent être élargis à d'autres types de données géographiques tels que les cartes, les tableaux et les textes.

Geografske informacije - Lociranje z geografskimi identifikatorji (ISO 19112:2019)

Ta standard določa pojmovno shemo lociranja na podlagi geografskih identifikatorjev. Vzpostavlja splošni model lociranja z uporabo geografskih identifikatorjev in opredeljuje sestavne dele sistema lociranja. Določa tudi pojmovno shemo geografskega leksikona. Lociranje s koordinatami je obravnavano v standardu ISO 19111. Vendar je v ta dokument vključen tudi mehanizem za beleženje dopolnilnih koordinatnih referenc. Ta dokument omogoča proizvajalcem podatkov, da določijo sisteme lociranja z uporabo geografskih identifikatorjev, in pomaga uporabnikom, da razumejo sistem lociranja, ki se uporablja v naborih podatkov. Omogoča dosledno sestavljanje geografskega leksikona in podpira razvoj drugih standardov na področju geografskih informacij. Ta dokument se uporablja za digitalne geografske podatke in v njem opisana načela lahko veljajo tudi za druge oblike geografskih podatkov, kot so zemljevidi, karte in dokumenti z besedilom.

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.

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

ISO 19112:2019(E)
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.

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.
