本技术报告采用ISO/TR 19167:2019，有助于理解as 19154中定义的无处不在的公共访问上下文信息模型，以建立UPA到地理信息环境。它说明了如何设计和实施UPA环境信息模型，以从基于地理信息系统的空气质量信息系统提供空气质量信息服务。关键词:无处不在的公共访问；地理信息；空气质量

This Technical Report adopts ISO/TR 19167:2019, which facilitates an understanding of the ubiquitous public access context information model, as defined in AS ISO 19154, to establish a UPA-to-geographic information environment. It illustrates how the UPA context information model is designed and implemented to provide an air quality information service from a geographic information system-based air quality information system. KEYWORDS: Ubiquitous public access; Geographic information; Air quality
