Intelligent transport systems - Geographic Data Files (GDF) - GDF5.0 (ISO 14825:2011)

ISO 14825:2011 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 ISO 14825:2011 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 ISO 14825:2011 are in-vehicle or portable navigation systems, traffic management centres, or services linked with road management systems, including the public transport systems.

Inteligentni transportni sistemi - Datoteke z geografskimi podatki (GDF) - GDF5.0 (ISO 14825:2011)

Ta mednarodni standard določa konceptualni in logični podatkovni model ter fizične kodirne formate za geografske podatkovne zbirke za aplikacije in storitve inteligentnih transportnih sistemov (ITS). Vključuje specifikacijo morebitne vsebine takih zbirk (podatkovni slovarji za značilnosti, lastnosti in razmerja), specifikacijo predstavitve takih vsebin in način določanja ustreznih informacij o sami zbirki (metapodatki).
Ta mednarodni standard se osredotoča na aplikacije in storitve ITS ter poudarja informacije o cestah in informacije, povezane s cestami. Poleg informacij o cestah in informacij, povezanih s cestami, so za aplikacije in storitve ITS potrebni še drugi podatki.
PRIMER 1: Pri aplikacijah in storitvah ITS so potrebne informacije o obravnavanih sistemih, da se določijo lokacije in/ali destinacije. Posledično so bistvenega pomena informacije o administrativnih in poštnih podrazdelitvah določenega področja.
PRIMER 2: Prikaz zemljevida je pomemben sestavni del aplikacij in storitev ITS.
Za pravilen prikaz zemljevida je bistvenega pomena vključitev kontekstualnih informacij o pojavih na zemeljskem in vodnem površju.
PRIMER 3: Podatki o interesnih točkah (POI) ali storitvah so glavna značilnost potovalnih informacij. Ti podatki aplikacijam in storitvam ITS za končnega uporabnika dodajajo vrednost.
Značilne aplikacije in storitve ITS, ki jih obravnava ta mednarodni standard, so navigacijski sistemi v vozilu ali prenosni navigacijski sistemi, centri za vodenje prometa ali storitve, povezane s sistemi upravljanja cest, vključno s sistemi javnega prevoza.
Konceptualni podatkovni model ima širši fokus kot aplikacije in storitve ITS. Je neodvisen od aplikacij, kar omogoča prihodnje usklajevanje tega mednarodnega standarda z drugimi standardi geografskih podatkovnih zbirk

ISO 14825:2011(E) vi © ISO 2011 – All rights reserved 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. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. 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. ISO 14825 was prepared by Technical Committee ISO/TC 204, Intelligent transport systems. This second edition cancels and replaces the first edition (ISO 14825:2004), which has been technically revised. SIST EN ISO 14825:2011

ISO 14825:2011(E) © ISO 2011 – All rights reserved vii Introduction By the late 1980s, producers and users of digital road map data became increasingly aware of the need for a common data interchange standard. Lack of such a standard was seen as an impediment to the commercial growth and success of industries using such data. Before the advent of the Intelligent Transport Systems (ITS) industry, development of spatial data interchange standards was done mostly on a regional basis and not designed for the specialised requirements of road-transport-related applications. The establishment of ISO/TC 204 in 1993 sought to remedy the lack of international standards for ITS. The technical committee is divided into 16 working groups. Working Group 3 (WG 3) was charged with the responsibility of developing standards to promote interchangeability of map data and interoperability of systems using map databases. The work of WG 3 started in 1994 with a review of the available regional standards documents, including standards developed by the Japan Digital Road Map Association (JDRMA) and developments in the US that resulted in the Spatial Data Transfer Standard (SDTS). European standardization efforts resulted in a standard called GDF3.0 (Geographic Data Files), which eventually was adopted as the basis for internationalized developments, leading to the publication of GDF4.0 in 2004. In the 1990s, the GDF standard was instrumental in enabling the European business-to-business (B2B) market for in-vehicle navigation in that it provided interoperability for exchanging digital map data between map manufacturers and navigation system integrators. The GDF specifications provided a base for both the capturing of geographic content and the exchanging of it. Its original design foresaw a powerful, application-independent model, while its initial rendition as a standard specifically addressed the requirements for the richness of navigable map databases. Since then, GDF has evolved in terms of boosted data modelling capabilities, broadened international applicability, expanded geographic domains, and diversified exchange formats. As a result, GDF covers a wide range of application domains and has been adapted to many geospatial technologies The current document presents the specification for GDF5.0, resulting from approximately 30 rounds of meetings held between 2001 and 2008 and involving experts from Australia, Canada, the Czech Republic, France, Germany, Japan, the Republic of Korea, the Netherlands, and the United States of America. Extensive activities towards harmonization with ISO/TC 211 standards were undertaken. Major GDF5.0 enhancements include UML model migration and refinements, harmonization with linear referencing and geospatial web standards, support for 3-D content and time coordinates, comprehensive character set and phonetic representations, and new XML- and SQL-based delivery formats. The specification of this International Standard is divided into several parts. After the introductory clauses, the overall conceptual data model is specified. In it, the basic building blocks of GDF and their interrelations are explained. It contains a specification of the different types of topology supported by this International Standard. It furthermore describes how database representations of real world objects, referred to as Features, are defined. It describes the characteristics of Features, called Attributes, and the topological and non-topological interrelations between Features. Finally, it describes the organization of the Features in GDF. Semantically, Features are organized in different Feature Themes. Logically and physically, Features are organized in Sections by area or in Layers by contents. In the Feature Catalogue, the different Features supported by this International Standard are defined. A special case is the Features from the Services Feature Theme. Because the requirements for this Feature Theme are highly market-oriented, the Services Feature Theme does not contain any normative Features, but contains an annex comprising an informative list of service definitions to assist users of this International Standard (see Annex C). In the Attribute Catalogue, the different characteristics of Features, called Attributes, are defined. A usage matrix outlines applicability of Attributes per Feature Theme and per Relationship. SIST EN ISO 14825:2011

ISO 14825:2011(E) viii © ISO 2011 – All rights reserved In the Relationship Catalogue, the different non-topological (i.e. semantic) Relationships which Features can have are defined. Relationships can relate Features of different Feature Themes, or those from the same or different Section and/or Layer. In the Feature representation rules, the possible geometrical ways in which the individual Features can be represented are specified for each topology type. This International Standard supports zero-, one- and two-dimensional primitives and up to four-dimensional coordinates. The specification of Features, Attributes and Relationships by no means dictates mandatory inclusion. The actual contents of GDF, apart from a minimum set of metadata elements as specified in the delivery formats, is not specified by this International Standard since this is considered to be an issue between clients and vendors. This International Standard allows the introduction of user-defined Features, Attributes and Relationships. In certain cases, different alternative ways of modelling and representation are offered. Representing Features in different geographical areas also may require the use of different basic representation mechanisms such as character sets, projection systems, etc. It is important that all these individual choices associated with GDF are specified. Furthermore, GDF should essentially be self-contained and be readable without any external specification. In order to make this possible, this International Standard specifies ways of describing GDF by means of metadata, captured by the Metadata Catalogue. Apart from providing a standard for the definition of geographic road databases, this International Standard also specifies mechanisms for data exchange and delivery. In o
