Overview
ISO 24099:2011 - Navigation data delivery structures and protocols defines the data structures and temporal protocols used in Intelligent Transport Systems (ITS) for delivering and updating map-related data from a Service Centre (SC) to In‑vehicle Systems (IVS). The standard covers message generation at the Service Centre and message reception at the IVS, and it supports delivery modes such as full replacements, incremental updates, and updates by geographic area. ISO 24099 focuses on map-related content (geometry, attributes, POI, status and emergency data) and relies on existing communication technologies; however, lower‑level communication protocols, non‑map content (e.g., standalone images), security mechanisms and business-transaction mechanisms are outside its scope.
Key Topics and Requirements
- Data structures: Defines classes and identifiers used for update targeting and content management (examples in Clause 9 include Area_ID, Content_ID, Version, Area_version, Content_version, Operation, Main_data).
- Protocol definitions: Provides protocol flows for IVS‑triggered and SC‑triggered updates, emergency data delivery and status updates (Clause 8 and Annex D).
- Update strategies: Supports complete area replacement, incremental feature/attribute changes, and selective content updates (Clause 7.2).
- Reference architecture: Offers an ITS reference architecture and framework concept to enable on‑board, off‑board and hybrid systems (Clause 7).
- Conformance & testing: Implementations claiming conformance must meet requirements in Clauses 8–9 and pass the abstract test suite in Annex A.
- UML modelling: Uses UML for message and structure diagrams (Clause 4 and Annex B).
- Version control & identifiers: Rules for specifying objects to be replaced/deleted and versioning management are specified (Clause 7.2.7).
Applications
ISO 24099 is practical for anyone building or operating dynamic navigation and map‑update services:
- Enabling over‑the‑air (OTA) map updates for automotive navigation systems.
- Supporting POI updates and delivery of time‑sensitive status or emergency data (traffic, hazards).
- Implementing hybrid map storage solutions (on‑board + off‑board) and minimizing data transfer via incremental updates.
- Creating interoperable ecosystems where multiple map suppliers, service centres and vehicle manufacturers exchange map content reliably.
Who uses this standard
- Automotive OEMs and telematics/system integrators
- Map data providers / Map centres
- Service Centre operators and content distribution platforms
- ITS solution architects and software developers
- Test houses verifying conformance to ITS update protocols
Related Standards (if applicable)
- Compatibility aimed with ISO Geographic Data Files (GDF) models.
- Designed to work with ITS communications protocols under ISO/TC 204 (e.g., WG 16 work).
- References ISO/TS 20452 for application categories (route planning, POI access, map display, etc.).
