地理信息定位服务

[中文适用范围]： 本文件规定了在位置提供设备与位置使用设备之间进行通信的接口的数据结构和内容，使位置使用设备能够获得和无歧义地解释位置信息，并根据可靠性的度量判断生成的位置信息是否满足预期用途的要求。标准化的定位接口允许从非特定定位技术中获取可靠的定位信息，并且在各种基于位置的信息应用（如测量、导航、智能交通系统(ITS)和基于位置的服务(LBS)）中有用。 [外文原描述]： This document specifies the data structure and content of an interface that permits communication between position-providing device(s) and position-using device(s) enabling the position-using device(s) to obtain and unambiguously interpret position information and determine, based on a measure of the degree of reliability, whether the resulting position information meets the requirements of the intended use. A standardized interface for positioning allows the integration of reliable position information obtained from non-specific positioning technologies and is useful in various location-focused information applications, such as surveying, navigation, intelligent transportation systems (ITS) and location-based services (LBS).
