16、 ISO 2008 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 interes
17、ted 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 C
18、ommission (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 tech
19、nical 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. ISO 17572-3 was prepared by Technical Committee ISO/TC 204, Intelligent transport systems. ISO 17572 consists of the follo
20、wing parts, under the general title Intelligent transport systems (ITS) Location referencing for geographic databases: Part 1: General requirements and conceptual model Part 2: Pre-coded location references (pre-coded profile) Part 3: Dynamic location references (dynamic profile) Licensed CopyChines

In a digital world, a real-world geographic object can be represent
22、ed by a feature in a geographic database. An example of a commonly known Location Reference is a postal address of a house. Examples of object instances include a particular exit ramp on a particular motorway, a road junction or a hotel. For efficiency reasons, Location References are often coded. T
23、his is especially significant if the Location Reference is used to define the location for information about various objects between different systems. For Intelligent Transport Systems (ITS), many different types of real-world objects will be addressed. Amongst these, Location Referencing of the ro
24、ad network, or components thereof, is a particular focus. Communication of a Location Reference for specific geographic phenomena, corresponding to objects in geographic databases, in a standard, unambiguous manner is a vital part of an integrated ITS system, in which different applications and sour
25、ces of geographic data will be used. Location Referencing Methods (LRM, methods of referencing object instances) differ by applications, by the data model used to create the database, or by the enforced object referencing imposed by the specific mapping system used to create and store the database.
26、A standard Location Referencing Method allows for a common and unambiguous identification of object instances representing the same geographic phenomena in different geographic databases produced by different vendors, for varied applications, and operating on multiple hardware/software platforms. If
27、 ITS applications using digital map databases are to become widespread, data reference across various applications and systems must be possible. Information prepared on one system, such as traffic messages, must be interpretable by all receiving systems. A standard method to refer to specific object
28、 instances is essential to achieving such objectives. Japan, Korea, Australia, Canada, the US and European ITS bodies are all supporting activities of Location Referencing. Japan has developed a Link Specification for VICS. In Europe, the RDS-TMC traffic messaging system has been developed. In addit
29、ion, methods have been developed and refined in the EVIDENCE and AGORA projects based on intersections identified by geographic coordinates and other intersection descriptors. In the US, standards for Location Referencing have been developed to accommodate several different Location Referencing Meth
30、ods. This International Standard provides specifications for location referencing for ITS systems (although other committees or standardization bodies may subsequently consider extending it to a more generic context). In addition, this version does not deal with public transport location referencing
31、; this issue will be dealt with in a later version. The International Organization for Standardization (ISO) draws attention to the fact that it is claimed that compliance with this document may involve the use of a patent concerning procedures, methods and/or formats given in this document in Claus
32、es 8 and 9 and Annexes A, B and C. ISO takes no position concerning the evidence, validity and scope of this patent right. The holder of this patent right has assured ISO that he/she is willing to negotiate licences under reasonable and non-discriminatory terms and conditions with applicants through

37、onal Standard specifies Location Referencing Methods (LRM) 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. This International Standard defines what is meant by such objects, and
38、 describes the reference in detail, including whether or not components of the reference are mandatory or optional, and their characteristics. This International Standard specifies two different LRMs: pre-coded location references (pre-coded profile); dynamic location references (dynamic profile). T
39、his International Standard does not define a physical format for implementing the LRM. However, the requirements for physical formats are defined. This International Standard does not define details of the Location Referencing System (LRS), i.e. how the LRMs are to be implemented in software, hardwa
40、re, or processes. This part of ISO 17572 specifies the dynamic location referencing method, comprising: attributes and encoding rules; logical data modelling; TPEG physical format specification for dynamic location references; coding Guidelines for Dynamic Location References; compressed Data Format
41、 Specification. It is consistent with other International Standards developed by ISO/TC 204 such as ISO 14825, Intelligent transport systems Geographic Data Files (GDF) Overall data specification. 2 Normative references The following referenced documents are indispensable for the application of this

44、g apply. 3.1 bearing angle between a reference direction and the direction to an object measured clockwise NOTE Unless otherwise specified, the reference direction is generally understood to be geographic north. 3.2 connection angle CA difference between side road bearing and bearing at a point 3.3
45、connection point location point captured in the location reference core, which forms the start point of a path external to the location NOTE 1 Connection points are used to connect a location reference extension to a location reference core and to connect linear locations to form a subnetwork. The c
46、onnection point is identified using its connection point index. NOTE 2 The connection point index is implicitly defined by the order of the points in a location reference. 3.4 connectivity status of being topologically connected NOTE In a graph two or more edges are said to be connected if they shar
47、e one or more nodes. 3.5 coordinate pair set of two coordinates (one longitude value and one latitude value), representing a position on the earth model NOTE Within the scope of this International Standard the earth model is embodied by ITRS and by ITRF coordinates. 3.6 core point CP point belonging
48、 to the location reference core 3.7 destination location location to be used as the end location of a journey for a route guidance application 3.8 extension point EP point belonging to the location reference extension 3.9 great circle circle on the surface of a sphere that has the same circumference
49、 as the sphere NOTE The connection between two points on a sphere along the great circle passing through said two points is the shortest connection (airline distance, or distance as the crow flies).
