NOTE Specific structure and contents of indoor positioning references depend on types of indoor positioning technologies. This document defines: a) the composition of an indoor map for indoor navigation of P/V ITS stations; b) the schema and encoding format of the indoor map for indoor navigation at the P/V ITS stations. This document focuses on the specification and format of the indoor map. The following issues which are adjunctive but essential for commercial navigation services are beyond the scope of this document: — authorized and authenticated access of users and services, including security; — payment; — preparation of indoor data which are necessary for indoor navigation; — low-level communication protocols required to transfer and share data from and to a roadside ITS station or a central ITS station; — other issues dependent on implementation of an instance of indoor navigation.

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.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types
of ISO document should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.

Introduction
With the spread of nomadic and mobile devices such as smart phones and the rapid expansion of indoor
spaces, many of the services and facilities related to the transport system have become accessible to indoor
spaces. Consequently, navigation in indoor space is considered a new killer application in the transport
industry.
The objective of this document is to provide a basic data model and encoding format for indoor positioning
reference data required for indoor navigation functionality for ITS applications. This document is intended
to be used by designers, developers and providers of indoor navigation services. When implemented, this
document is intended to:
1) provide developers and designers with concepts and appropriate information to implement indoor
navigation services;
2) provide developers and designers with interoperable ways to use indoor navigation data from various
sources for indoor navigation;
3) enable the provision of indoor navigation services to users;
4) provide developers and designers with an extendable base for indoor navigation.

Part 2:
Requirements and specification for indoor maps
1 Scope
This document defines requirements and specifications of indoor positioning references, which can be
referenced for positioning in indoor space, for supporting indoor navigation functionality of a personal/
vehicle (P/V) ITS station.
NOTE Specific structure and contents of indoor positioning references depend on types of indoor positioning
technologies.
This document defines:
a) the composition of an indoor map for indoor navigation of P/V ITS stations;
b) the schema and encoding format of the indoor map for indoor navigation at the P/V ITS stations.
This document focuses on the specification and format of the indoor map. The following issues which are
adjunctive but essential for commercial navigation services are beyond the scope of this document:
— authorized and authenticated access of users and services, including security;
— payment;
— preparation of indoor data which are necessary for indoor navigation;
— low-level communication protocols required to transfer and share data from and to a roadside ITS station
or a central ITS station;
— other issues dependent on implementation of an instance of indoor navigation.
