地理信息.地点标识符(PI)架构

[中文适用范围]： 本标准规定了一种架构，定义了用于地点标识符的参考模型和编码方法。本标准中的“地点”概念不仅包括现实世界中的地点，还包括虚拟世界中的地点。这些“地点”使用坐标标识符、地理标识符或虚拟世界标识符（如URI）进行标识。在本标准中，地点的标识符称为地点标识符（PI）。 参考模型定义了一种机制，用于将多个地点标识符匹配到同一地点。此外，参考模型还定义了数据结构和一组服务接口。 本标准适用于基于位置的服务、应急管理服务以及其他需要跨特定领域使用坐标、地理或虚拟世界标识符表示地点描述的通用架构的应用领域。 本标准不涉及生成任何特定类型的地点描述，也不涉及定义已定义地点的唯一标准化描述，如地址编码方案。 [外文原描述]： ISO 19155:2012 specifies an architecture that defines a reference model with an encoding method for an identifier of a place. The concept of "place" within ISO 19155:2012 includes "places" not only in the real world but also those in the virtual world. These "places" are identified using either coordinate identifiers, geographic identifiers, or virtual world identifiers such as URI. In ISO 19155:2012, an identifier of a place is referred to as a Place Identifier (PI). The reference model defines a mechanism to match multiple Place Identifiers to the same place. In addition, a data structure and set of service interfaces are also defined in this reference model. ISO 19155:2012 is applicable to location based services, emergency management services and other application domains that require a common architecture, across specific domains, for the representation of place descriptions using coordinate, geographic, or virtual world identifiers.
