Geographic information - Positioning services (ISO 19116:2019)

This standard specifies the data structure and content of an interface that permits communication between position-providing device(s) and position-using device(s) enabling the position-using device(s) to obtain and unambiguously interpret position information and determine, based on a measure of the degree of reliability, whether the resulting position information meets the requirements of the intended use. A standardized interface for positioning allows the integration of reliable position information obtained from non-specific positioning technologies and is useful in various location-focused information applications, such as surveying, navigation, intelligent transportation systems (ITS), and location-based services (LBS).

Geoinformation - Positionierung (ISO 19116:2019)

Information géographique - Services de positionnement (ISO 19116:2019)

Le présent document indique la structure des données et le contenu d'une interface qui permet la communication entre un ou plusieurs dispositifs de mesure de position et un ou plusieurs dispositifs utilisant les données de position de sorte que ces derniers puissent obtenir et interpréter les informations de position sans ambiguïté et déterminer, en se fondant sur une mesure du degré de fiabilité, si les informations de position qui en résultent répondent aux exigences de l'utilisation prévue.
Une interface normalisée de positionnement permet l'intégration d'informations de position fiables obtenues à partir de technologies de positionnement non spécifiques et est utile dans diverses applications utilisant des informations ciblées géographiquement, comme l'arpentage, la navigation, les systèmes de transport intelligents (STI) et les services géoréférencés (LBS).

Geografske informacije - Lokacijske storitve (ISO 19116:2019)

Ta standard določa strukturo podatkov in vsebino vmesnika za komunikacijo med napravami, ki zagotavljajo položaj, in napravami, ki uporabljajo položaj. Omogoča, da naprave, ki uporabljajo položaj, pridobijo in nedvoumno razlagajo informacije o položaju ter na podlagi stopnje zanesljivosti določijo, ali pridobljena informacija o položaju ustreza zahtevam predvidene uporabe. Standardiziran vmesnik za določanje položaja omogoča integracijo zanesljivih informacij o položaju, pridobljenih iz nespecifičnih tehnologij za pozicioniranje in je uporaben za različne lokacijsko usmerjene vrste uporabe informacij, kot so opazovanje, navigacija, inteligentni transportni sistemi (ITS) in lokacijske storitve (LBS).

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 second edition cancels and replaces the first edition (ISO 19116:2004), which has been technically

revised.
The main changes compared to the previous edition are as follows.

— Device specific definitions have been removed from the model and normative body of the document.

These have been clarified and reformatted in Annex D.

— Constructs from withdrawn standards ISO 19113, ISO 19114, and ISO 19115 have been updated

where necessary to ISO 19115-1 and ISO 19157. References to these new standards are carried out

using approved methods.

— Terminology entries from the first edition were updated and harmonized with other current

standards in ISO/TC 211. As per ISO/IEC Directives, Part 2, 2018, unused terms have been removed

from this edition.

— Constructs from ISO 19111 have been updated. References to the revised ISO 19111:2019 document

are carried out using approved methods.

— A new, convenient yet unobtrusive, set of constructs for determining the reliability of a positioning

result have been added to the model, in Clause 8.

— Based on the concepts related to the model, conformance with the other standards, and separation

of the technology specific content from the abstract model, all UML models have been updated.

— Original requirements “drafted as normative shall statements” were rechecked for consistency

with the model. Where necessary the requirements were revised or retained as regular text.

— Significant editorial revisions have been carried out, clarifying the structure of the document,

correction of errors, and following current ISO/IEC Directives, Part 2 for drafting specifications.

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

Introduction

Positioning services are among the processing services identified in ISO 19119:2016. Processing

services include services that are computationally oriented and operate upon the elements from the

model domain, rather than being directly integrated in the model domain itself. This document defines

and describes the positioning service.

Positioning services employ a wide variety of technologies that provide position and related information

to a similarly wide variety of applications, as depicted in Figure 1. Although these technologies differ in

many respects, there are important items of information that are common among them and serve the

needs of these application areas, such as the position data, time of observation and its accuracy. Also,

there are items of information that apply only to specific technologies and are sometimes required in

order to make correct use of the positioning results, such as signal strength, geometry factors, and raw

measurements. Therefore, this document includes both general data elements that are applicable to a

wide variety of positioning services and technology specific elements that are relevant to particular

technologies.
Figure 1 — Positioning services overview

Electronic positioning technology can measure the coordinates of a location on or near the Earth with

great speed and accuracy, thereby allowing geographic information systems to be populated with

any number of objects. However, the technologies for position determination have neither a common

structure for expression of position information, nor common structures for expression of accuracy

and reliability. The positioning services interface specified in this document provides data structures

and operations that allow spatially oriented systems to employ positioning technologies with greater

efficiency and interoperability.

Geographic information — Positioning services
1 Scope

This document specifies the data structure and content of an interface that permits communication

between position-providing device(s) and position-using device(s) enabling the position-using device(s)

to obtain and unambiguously interpret position information and determine, based on a measure of

the degree of reliability, whether the resulting position information meets the requirements of the

intended use.

A standardized interface for positioning allows the integration of reliable position information obtained

from non-specific positioning technologies and is useful in various location-focused information

applications, such as surveying, navigation, intelligent transportation systems (ITS), and location-

based services (LBS).
