ISO/TC 204/WG 3 - ITS geographic data

The ISO 17572 series specifies location referencing methods (LRMs) that describe locations in the context of geographic databases and that are intended for use in locating transport-related phenomena both in an encoder system and from the decoder side. This document defines what is meant by such objects and describes the reference in detail, including whether or not components of the reference are mandatory or optional, and their characteristics. The ISO 17572 series specifies three different LRMs: — pre-coded LRM (pre-coded profile); — dynamic LRM (dynamic profile); — precise relative LRM (precise relative profile). The ISO 17572 series does not define a physical format for implementing the LRM. However, the requirements for physical formats are defined. The ISO 17572 series does not define details of the location referencing system (LRS), i.e. how the LRMs are to be implemented in software, hardware or processes. This document specifies the following general LRM-related subjects: — requirements of an LRM; — conceptual data model for LRMs; — inventory LRMs (see Annex A). This document also provides: — examples of conceptual model use (see Annex B); — a comparison of definitions with ISO/TC 211 (see Annex C).

This document specifies the conceptual and logical data model in addition to the physical encoding formats for geographic databases for Intelligent Transport Systems (ITS) applications and services. This document includes a specification of potential contents of such databases (data dictionaries for Features, Attributes and Relationships), a specification of how these contents are to be represented, and how relevant information about the database itself can be specified (metadata). This document further defines map data used in automated driving systems, Cooperative-ITS, and Multi-modal transport. The focus of this document is firstly on emerging ITS applications and services, such as Cooperative-ITS and automated driving systems, and it emphasizes road, lane and relevant information on road and lane. However, ITS applications and services also require other information in addition to road and road-related information, which are provided as external databases to connect with GDF and to complement each other. Highly defined public transport databases, for instance, are indispensable in multi-modal transport applications and services in particular. Thus, this document focuses secondly on an expansion of the specification to connect with externally existing databases. It is particularly designed to connect a Transmodel (EN 12896-1 and EN 12896-2) conformant public transport database. Typical ITS applications and services targeted by this document are in-vehicle or portable navigation systems, traffic management centres, or services linked with road management systems, including public transport systems. The conceptual data model specified here has a broader focus than ITS applications and services. It is application independent, allowing for future harmonization of this model with other geographic database standards.

This document describes and lists the characteristics of the Precise Relative Location Referencing Method (PRLRM) which describes precise relative locations in the context of geographic databases and is used to locate transport-related objects in an encoder system as well as in the decoder side. This document does not define a physical format for implementing the PRLRM. However, the requirements for physical formats are defined. This document does not define details of the Precise Relative Location Referencing System (PRLRS), i.e. how the PRLRM is to be implemented in software, hardware or processes. This document specifies PRLRM, comprising: — conceptual data model for Location Referencing Methods (LFMs); — specification of location referencing for precise relative information; — use cases for Precise Relative Location References (informative Annex C); — use cases for elements of Precise Relative Location References (informative Annex D); — implementation of Precise Relative Location References (Japanese example) (informative Annex E). This document defines methods that enable exchange location information of the object to be referenced in the lane or the lane junction. This document does not specify the road (link) on which the object of reference exists.

This document specifies the conceptual and logical data model and physical encoding formats for geographic databases for Intelligent Transport Systems (ITS) applications and services. It includes a specification of potential contents of such databases (data dictionaries for Features, Attributes and Relationships), a specification of how these contents shall be represented, and of how relevant information about the database itself may be specified (metadata). The focus of this document is on ITS applications and services and it emphasizes road and road-related information. ITS applications and services, however, also require information in addition to road and road-related information. EXAMPLE 1 ITS applications and services need information about addressing systems in order to specify locations and/or destinations. Consequently, information about the administrative and postal subdivisions of an area is essential. EXAMPLE 2 Map display is an important component of ITS applications and services. For proper map display, the inclusion of contextual information such as land and water cover is essential. EXAMPLE 3 Point-of-Interest (POI) or service information is a key feature of traveller information. It adds value to end-user ITS applications and services. Typical ITS applications and services targeted by this document are in-vehicle or portable navigation systems, traffic management centres, or services linked with road management systems, including public transport systems. The Conceptual Data Model has a broader focus than ITS applications and services. It is application independent, allowing for future harmonization of this document with other geographic database standards.

This document defines a shareable geospatial database service framework and provides an overview of the ISO 19297 series of standards. This is intended to enhance user accessibility and interoperability of databases. It does not cover ITS applications or service specific issues.

This document is a compilation of terms to be contained in a spatio-temporal data dictionary for cooperative-ITS and automated driving systems. This data dictionary includes static data (e.g. map, road signs and buildings) and dynamic data (e.g. traffic condition, accident reports). This document is an updated and expanded version of ISO/TR 21718:2017.

The ISO 17572 series specifies location referencing methods (LRMs) that describe locations in the context of geographic databases and will be used to locate transport-related phenomena in an encoder system as well as in the decoder side. The ISO 17572 series defines what is meant by such objects and describes the reference in detail, including whether or not components of the reference are mandatory or optional, and their characteristics. The ISO 17572 series specifies two different LRMs: -pre-coded location references (pre-coded profile); -dynamic location references (dynamic profile). The ISO 17572 series does not define a physical format for implementing the LRM. However, the requirements for physical formats are defined. ISO 17572-3:2014 does not define details of the location referencing system (LRS), i.e. how the LRMs are to be implemented in software, hardware, or processes.

ISO 24099:2011 defines the data structures and protocol(s) used in intelligent transport system (ITS) applications for the delivery and update of map-related data from Service Centre (SC) to users [(In-vehicle Systems (IVS)]. ISO 24099:2011 also specifies the message generation protocols in the Service Centre and the message receiving protocols in the In‑vehicle Systems. The map centre specified in ISO 24099:2011 represents the supplier of map data and the Service Centre provides data and services to user devices. The term protocol as used in ISO 24099:2011 is a temporal sequence of map-related data interactions between system components that implement map-related data delivery and update. The delivery and update of map-related data rely on existing communication technology. The protocols associated with communication technology, and the other application control protocols and non-map-related data, for example images to display independent of the map database such as HTML images, are outside the scope of ISO 24099:2011. Definitions of security mechanisms and business transaction mechanisms are also outside the scope of ISO 24099:2011.

ISO 17267:2009 specifies an application programming interface (API) for navigation systems. It specifies the data that may be retrieved from the map database and defines the interface for access. This International Standard specifies a set of function calls. It also specifies the design of the API and gives examples of its intended use. Furthermore, it gives the criteria to determine whether a data access library is in accordance with this International Standard. ISO 17267:2009 is applicable to the following functional categories of navigation applications: positioning; route planning; route guidance; map display; address location; services and point of interest (POI) information access.
