ISO 19154:2014定义了地理信息普遍公共访问（UPA）的参考模型。这个参考模型使用了开放式分布式处理？ISO/IEC 10746-1和ISO 19101中的参考模型（RM-ODP）。 ISO 19154:2014中规定的参考模型定义如下: ?地理信息普遍公共访问（UPA）的概念模型； ?支持该领域当前和未来规范开发的参考模型和框架； ?地理信息UPA系统和服务中的信息和处理语义； ?本国际标准与其他ISO地理信息标准之间的体系结构关系。 ISO 19154适用于基于位置的服务（LBS）、无处不在的计算环境、链接的开放数据以及其他需要无缝公共访问地理信息的领域。 尽管ISO 19154:2014是在信息技术和信息技术标准的背景下构建的，但它独立于任何应用程序开发方法或技术实现方法。

ISO 19154:2014 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 ISO 19154:2014 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. ISO 19154 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, ISO 19154:2014 is independent of any application development method or technology implementation approach.
