Overview
ISO/TR 19167:2019 - "Application of ubiquitous public access to‑geographic information to an air quality information service" explains how the Ubiquitous Public Access (UPA) context information model (defined in ISO 19154) can be applied to design and implement a GIS‑based air quality information service. The technical report clarifies the UPA‑to‑GI (UPA to Geographic Information) environment, presents a sample air quality context information model (locational, geospatial and geosemantic packages), and documents a proof‑of‑concept deployment in Seoul. The document is informative (no normative references) and targets interoperable, public‑facing geographic information services for air quality.
Key topics and requirements
- UPA context information model (ISO 19154): core concept used to gather and manage geographic context so services can adapt to user location, device and interest criteria.
- UPA‑to‑GI architecture: design principles for enabling ubiquitous public access to geographic data and services irrespective of user device or location.
- Air quality context packages: breakdown into locational, geospatial, and geosemantic context packages tailoring ISO 19154 to air quality information.
- System components: integration of air quality observation systems (sensors, GNSS), GIS‑based air quality information systems, and user interfaces (web/mobile).
- Data sources: support for diverse sources - physical sensors, portable sensors, citizen‑generated data and social media (semantic/social sensors).
- Air quality indicators: treatment of indices such as AQI/Comprehensive Air Quality Index (CAI) for public communication.
- Interoperability and public access: emphasis on open access, data sharing, and linking geodata (examples cited include RDF/OWL transformations).
- Use cases & implementation guidance: diagrams and implementation notes showing how to realize UPA‑based air quality services.
Applications - who uses this standard
- Environmental agencies and regulators implementing public air quality reporting platforms.
- GIS and SDI architects designing interoperable spatial data infrastructures for air quality monitoring (e.g., INSPIRE aligned systems).
- Smart city and IoT teams integrating sensor networks and GNSS‑enabled mobile sensing.
- Software developers building public web/mobile air quality apps and APIs (AQ mobile apps, open data platforms).
- Researchers and urban planners studying citizen science, social media sensing and public engagement in air quality governance.
Related standards
- ISO 19154 (UPA context information model) - primary reference for UPA‑to‑GI architecture.
- ISO 19156 (observations and measurements) and other ISO/TC 211 standards - relevant for sensor and GIS interoperability.
