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 documents 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).
Attention is drawn to the possibility that some of the elements of this document may be the subject of

Introduction
Recent advances of web-based and mobile computing technologies have ushered in an era where the general
public are not only consumers of content, but also act as creators or providers of new, enriched content.
One sector in particular that is experiencing rapid change and growth is that of geographic information.
“Location” in a general sense is one of the basic requirements of all mobile users. In early development,
users were only “consuming” location-based content, but with ever increasingly sophisticated mobile
hardware devices and the ever expanding extent of telecommunications networking and sensor web
enabled infrastructure, mobile users are now able to create many types of geographic data. Creation
of content can be on an individual level, using a coordinate location to enable navigation to a new café
described in a blog entry, or as a collaborative effort, such as collecting GPS tracks and incorporating
them into the Open Street Map project.
Smaller devices, embedded systems, wireless communication, and sensor networks (ubiquitous
computing technologies) require methods of handling geographic information in terms of both
production and consumption. Beyond the previously limited public consumption of geographic
information, ubiquitous computing technologies provide the infrastructure for the general public to
produce, distribute, and consume geographic information. These concepts are manifested as “seamless
access from anywhere and at any time to easy-to-use geographic information and services”. We refer to
these concepts as Ubiquitous Public Access to geographic information.
The goal of ubiquitous public access to geographic information (UPA-to-GI) is to make the user
experience of any “smart” device intuitive to understand, along with being easy to use. To achieve this
goal, contextual information that is gathered from varied sources is managed efficiently within the
UPA architecture. Therefore, systems or services for UPA to geographic information need to support a
delivery mechanism of contextual information.
This International Standard defines the requirements of standardization for systems and services
supporting ubiquitous public access to geographic information, and describes a comprehensive set of
fundamental facets that specify an abstract description of the elements for UPA to geographic information.
This International Standard further establishes a series of models comprised as a conceptual framework
that, when implemented, will support the development of a set of systems and services for enabling
ubiquitous public access to geographic information. In a UPA environment, general users are no longer
only passive consumers of geographic information, but rather active participants in several steps of the
data and information management lifecycle such as collection, creation and capture, and/or use and
dissemination.
Ubiquitous public access to geographic information might be thought of as a type of geographic
information service. However, the currently available standards used in mobile environments are based
on web technologies which are not efficient enough to handle the requirements of UPA. In order to
provide relevant geographic information to users, the context of the users is described.
The reference model specified here defines a group of models which form a framework that supports
methods of extracting geographically explicit context information from varied information sources,
such as a lexicon, photos, videos, and others sources. Additional models in the framework specify how
geographic data produced and distributed by the general public can be semantically linked to meet
the user’s contextual requests, and how heterogeneous geographic content can be seamlessly accessed,
integrated, and provided to a user regardless of the kind of device the user operates.
INTERNATIONAL STANDARD ISO 19154:2014(E)
Geographic information — Ubiquitous public access —
Reference model
1 Scope
This International Standard defines a reference model for ubiquitous public access (UPA) to geographic
information. This reference model uses standard concepts from both the Open distributed processing
— Reference model (RM-ODP) in ISO/IEC 10746-1 and ISO 19101.
The reference model specified in this International Standard defines the following:
— conceptual models for ubiquitous public access (UPA) to geographic information;
— a reference model and framework to support current and future specification development in this area;
— the semantics of information and processing within systems and services for the UPA of
geographic information;
— the architectural relationship between this International Standard and other ISO geographic
information standards.
This International Standard is applicable to location-based services (LBS), ubiquitous computing
environments, linked open data, and other domains that require a seamless public access to
geographic information.
Although structured in the context of information technology and information technology standards,
this International Standard is independent of any application development method or technology
implementation approach.
2 Conformance
General conformance and testing requirements are defined in ISO 19105. Conformance requirements
