ISO publishes location referencing standards series 17572

ISO has now published the standards series 17572 'Intelligent transport systems (ITS) -- Location referencing for geographic databases' which includes dynamic location referencing and describes the DLR1 method known as AGORA-C.

You can find the standards series for purchase on the ISO site:

Bosch, who submitted the standard series, discovered one error in the document ISO 17572-3 which was introduced during the publishing process. They are currently checking with the ISO secretariat how to proceed to add a corrigendum. In the meantime you can see the intended correction here:

As described on the ISO site:

ISO 17572 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. It 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.

It specifies two different LRMs:

• pre-coded location references (pre-coded profile);
• dynamic location references (dynamic profile).

It does not define a physical format for implementing the LRM. However, the requirements for physical formats are defined.

It 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 17572-1:2008 specifies the following general LRM related sections:

• requirements to a Location Referencing Method;
• conceptual Data Model for Location Referencing Methods;
• ‎inventory of Location Referencing Methods;
• ‎examples of Conceptual Data Model Use;
• ‎description of selected UML Elements;
• ‎comparison of Definitions with ISO/TC 211;
• ‎introduction to the TPEG Physical Format.

ISO 17572-2:2008 specifies the pre-coded location referencing method, comprising:

• specification of pre-coded location references (pre-coded profile);
• logical format for VICS link location;
• TPEG physical format for ALERT-C-location references;
• TPEG physical format for Korean node-link ID references.

ISO 17572-3:2008 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 specification.
