Intelligent transport systems - Geographic Data Files (GDF) GDF5.1 - Part 2: Map data used in automated driving systems, Cooperative ITS, and multi-modal transport (ISO 20524-2:2020)
This standard 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 can be specified (metadata).
The focus of this standard 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.
Typical ITS applications and services targeted by this International Standard 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 standard with other geographic database standards.
In order to deal with a multiple data provider environment and new applications, conceptual models, features, attributes and relationships are expanded in GDF5.1.
GDF5.1 is separated into two parts according to methods of utilization.
GDF5.1 Part 1 defines application-independent map data shared between multiple sources.
GDF5.1 Part 2 defines map data used in automated driving systems, cooperative ITS, and multi-modal transport.

Systèmes de transport intelligents - Fichiers de données géographiques (GDF) GDF5.1 - Partie 2 : Données cartographiques utilisées dans les systèmes de conduite automatisée, les ITS coopératifs et le transport multimodal (ISO 20524-2:2020)
Le présent document spécifie le modèle de données conceptuel et logique, venant s’ajouter aux formats de codage physique pour les bases de données géographiques destinées aux applications et services pour Systèmes de transport intelligents (STI). Il comporte une spécification du contenu potentiel de ces bases de données (dictionnaires de données pour les Entités, Attributs et Relations), une spécification de la manière dont leur contenu doit être représenté et de la façon dont les informations pertinentes relatives à la base de données elle-même peuvent être spécifiées (métadonnées). Ce document définit également les données cartographiques utilisées dans les systèmes de conduite automatisée, les STI coopératifs et le transport multimodal.
Le présent document se concentre tout d’abord sur les applications et services STI émergents, tels que les STI coopératifs et les systèmes de conduite automatisée, et il met l’accent sur la route, la voie de circulation et les informations pertinentes sur la route et la voie de circulation. Cependant, les applications et les services STI nécessitent également d’autres informations en plus des informations sur les routes et des informations liées aux routes, qui sont fournies sous forme de bases de données externes à relier à GDF, ces différentes bases de données devant se compléter mutuellement. Des bases de données à haute résolution dans le domaine des transports publics sont, par exemple, indispensables, notamment dans les applications et services de transport multimodal. C’est pourquoi ce document se concentre en second lieu sur une extension de la spécification en vue d’assurer une connexion avec des bases de données externes existantes. Le document est particulièrement conçu pour connecter une base de données de transport public conforme à Transmodel (EN 12896‑1 et EN 12896‑2).
Les applications et services STI typiques ciblés par le présent document sont les systèmes de navigation embarqués ou portatifs, les systèmes de gestion du trafic ou les services liés aux systèmes de gestion de la circulation routière, y compris les systèmes de transport public.
Le modèle de données conceptuel spécifié dans le présent document a une portée plus étendue que les applications et services STI. Il est indépendant des applications et permettra une future harmonisation du présent modèle avec d’autres normes relatives aux bases de données géographiques.
Inteligentni transportni sistemi - Datoteke z geografskimi podatki (GDF) - GDF5.1 - 2. del: Podatki zemljevidov, ki se uporabljajo v sistemih za avtomatizirano vožnjo, v kooperativnem ITS in multimodalnem transportu (ISO 20524-2:2020)
Ta standard določa konceptualni in logični podatkovni model in fizične formate kodiranja za zbirke geografskih podatkov za aplikacije in storitve inteligentnih transportnih sistemov. Vsebuje specifikacijo možnih vsebin tovrstnih podatkovnih zbirk (podatkovni slovarji za funkcije, atribute in razmerja), specifikacijo za način predstavitve teh vsebin in možnosti specifikacije pomembnih informacij o sami podatkovni zbirki (metapodatki).
Ta standard se osredotoča na uporabo in storitve inteligentnih transportnih sistemov in daje poudarek na cestne in s tem povezane informacije. Aplikacije in storitve inteligentnih transportnih sistemov pa prav tako poleg cestnih in s tem povezanih informacij potrebujejo druge informacije.
Tipične aplikacije in storitve inteligentnih transportnih sistemov, ki jih obravnava ta mednarodni standard, so vgrajeni ali prenosni navigacijski sistem, centri za upravljanje prometa ali storitve, povezane s sistemi cestnega upravljanja, vključno s sistemi javnega prevoza.
Konceptualni podatkovni model se uporablja širše kot aplikacije in storitve inteligentnega transportnega sistema. Ta model je namreč neodvisen od aplikacij in omogoča prihodnje usklajevanje tega standarda z drugimi standardi s področja geografskih podatkovnih zbirk.
Da bi bilo mogoče obravnavati okolje z več ponudniki podatkov in novimi aplikacijami, so konceptualni modeli, funkcije, atributi in razmerja razširjena v datoteki z geografskimi podatki GDF5.1.
Datoteka GDF5.1 je razdeljena na dva dela glede na metode uporabe.
1. del datoteke GDF5.1 določa kartografske podatke, ki so neodvisni od aplikacij, in se jih deli med več viri.
2. del datoteke GDF5.1 določa kartografske podatke, ki se uporabljajo v sistemih avtonomne vožnje, kooperativnem inteligentnem transportnem sistemu in multimodalnem prevozu.
