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.

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.
