Full title and description

Intelligent transport systems (ITS) — Location referencing for geographic databases — Part 1: General requirements and conceptual model. This part of ISO 17572 defines general requirements, the conceptual data model and terminology for location referencing methods (LRMs) used to describe locations in the context of geographic databases for ITS encoder/decoder systems.

Abstract

The ISO 17572-1:2022 document specifies the overall requirements and conceptual model for Location Referencing Methods (LRMs) intended to locate transport-related phenomena in encoder and decoder systems. It defines the objects and components of location references and indicates whether components are mandatory or optional. The 17572 series (as reflected in Part 1) covers multiple LRM profiles — pre-coded, dynamic and precise relative — and provides conceptual modelling, an inventory of LRMs, examples of model use and comparison of definitions with related ISO/TC 211 work.

Scope

ISO 17572-1:2022 establishes the general requirements and the conceptual data model for location referencing methods applied to geographic databases used in intelligent transport systems. It is intended to ensure consistent definition and exchange of location references between encoders and decoders, to inventory and describe LRM components and behaviour, and to provide informative annexes (examples, inventory and comparison with ISO/TC 211). The part does not prescribe a single physical format but defines requirements that physical implementations should meet.

Key topics and requirements

• Definition of Location Referencing Methods (LRMs) and their required components.
• Conceptual data model for LRMs (UML/logical modelling of reference objects and attributes).
• Specification and inventory of LRM profiles — pre-coded, dynamic and precise relative (precise relative profile introduced in the series).
• Requirements for physical formats (requirements are specified, though the standard does not mandate a single physical encoding).
• Examples of conceptual model usage and informative annexes (inventory, examples, and comparison with ISO/TC 211 definitions).

Typical use and users

This standard is used by ITS standards developers, mapping and GIS data providers, traffic management and control centres, navigation and fleet-management software vendors, telematics and location-based service engineers, and organizations implementing encoder/decoder systems for traffic and transport information exchange. It supports interoperability between location reference producers and consumers across countries and systems.

Related standards

ISO 17572-1 is part of the ISO 17572 series. Other relevant parts include ISO 17572-2 (Pre-coded location references / pre-coded profile) and ISO 17572-3 and -4 (dynamic and precise relative profiles; related parts in the series cover specific LRM profiles and physical formats). Implementers will often use Part 1 together with the applicable profile part(s) (for example Part 2 for pre-coded references or Part 4 for precise relative references).

FAQ

Q: What is this standard?

A: ISO 17572-1:2022 is Part 1 of the ISO 17572 series for Intelligent Transport Systems; it defines general requirements and the conceptual model for location referencing methods used with geographic databases.

Q: What does it cover?

A: It covers the definition and conceptual modelling of LRMs, mandatory/optional components of location references, an inventory of LRM elements, and informative examples and comparisons with ISO/TC 211 definitions; it also sets out requirements that physical encodings should meet without mandating a single encoding format.

Q: Who typically uses it?

A: ITS standardizers, GIS and mapping data suppliers, navigation and telematics vendors, traffic management authorities, and software engineers who need interoperable location referencing between encoders and decoders.

Q: Is it current or superseded?

A: ISO 17572-1:2022 is the published (current) edition from July 2022 and replaces earlier editions (for example the 2015 edition).

Q: Is it part of a series?

A: Yes — it is Part 1 of the ISO 17572 series. Other parts (e.g., Part 2, Part 3/4) describe specific LRM profiles and physical format guidance. Implementers should consult the relevant profile parts in conjunction with Part 1.

Q: What are the key keywords?

A: Location referencing, LRM, ITS, geographic database, pre-coded, dynamic, precise relative, conceptual data model, encoder, decoder, LRS, TPEG.
