28、29 BS EN ISO 14825:2011ISO 14825:2011(E) vi ISO 2011 All rights reservedForeword 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 tech
29、nical 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
30、 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 I
31、nternational 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
32、 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
33、technically revised. BS EN ISO 14825:2011ISO 14825:2011(E) ISO 2011 All rights reserved viiIntroduction 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 t
34、he 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 app
35、lications. 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
36、 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 Standa
37、rd (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 Europe
38、an 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 i
39、t. 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 internationa
40、l 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 meeti
41、ngs 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 enhanc
42、ements 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 Inter
43、national 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 Internatio
44、nal 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 organiz
45、ation 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 spec
46、ial 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 thi
47、s 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. BS EN ISO 14825:2011ISO 14825:2011(E) viii ISO 2011 All rights re
48、servedIn 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 poss
49、ible 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 vendo
