Abstract
The advance in Information Communication Technology (ICT) has contributed to global challenges of improving urban air quality. Ubiquitous computing technology enables citizens to easily access air quality information services without spatial or temporal limitations. Citizens are also encouraged to participate in air quality assessment and environmental governance. These societal and technical changes require a new paradigm to develop an air quality information system and its services. An air quality information system needs to integrate varied types of air quality information from heterogeneous data sources as well as allow citizens to express their concerns about air quality. Thus, a standardized manner is necessary to develop an air quality information system. In this regard, an air quality context information model was designed according to the Ubiquitous Public Access (UPA) context information model defined in the International Organization for Standard (ISO) 19154. For validation and verification purposes, the air quality context information model was implemented in a geographic information system (GIS)-based air quality information system. Implementation results showed that spatially relevant air quality information services were generated from the system, depending on the location and air quality situations near a specific user. Also, citizens can contribute air quality information at their current regions.

ISO/TC 211 Geographic information/Geomatics, which is a technical committee within ISO for standardization in the field of digital geographic information [27], recently presented ISO 19154 “Geographic information - Ubiquitous public access - Reference model” in 2014 [26]
In the Ubiquitous Public Access (UPA) geospatial context information model, the locational entity is allocated the geospatial representation type inferred by its locational contexts
Summary
Rapid urbanization and industrialization have led to severe deterioration in the atmospheric environments of major cities [1,2]. To sustainably support citizens’ contribution and participation in societal environmental decision, the air quality information system needs to efficiently maintain and integrate air quality data from various sensing systems, and to allow for citizens to provide and obtain air quality information services. The GIS-based air quality information is implemented for citizens to access air quality information regardless of their locations and devices in use. With these applications, citizens can provide their concerns about air quality at their current regions.
