ISO/TS 21219-21:2018定义了一种使用地理位置参考(GLR)的方法,可供相关TPEG应用程序使用。本文件中定义了GLR类型。它用于定义地理位置参照(点、多段线和地理区域)。GLR方法旨在成为可在TPEG位置参考容器(TPEG-LRC)内运输的方法之一,用于提供主要地理位置(如天气)信息的TPEG应用。GLR规范旨在保持基本和紧凑,因此它也可以有利地应用于非导航设备中,用于简单的TPEG服务,如天气信息、安全警报等。因此,GLR位置参考方法旨在补充与地图相关的位置参考方法,其中重点是道路和公路等人造物品的参考。基于上述理由,GLR的范围仅限于地球表面的地理位置。
ISO/TS 21219-21:2018 defines a method of using geographic location referencing (GLR) that can be used by relevant TPEG applications. The GLR type is defined in this document. It is used for defining geographic location references (points, polylines, and geographical areas). The GLR method is intended to be one of the methods that can be transported inside a TPEG-location referencing container (TPEG-LRC) for those TPEG applications providing information for primarily geographical locations (e.g. weather).The GLR specification is kept basic and compact on purpose, such that it can also be employed advantageously in non-navigation devices for simple TPEG services such as weather information, safety alerts, etc. As such, the GLR location referencing method is intended to be complementary to map-related location referencing methods, where the focus rather is on the referencing of man-made artefacts such as roads and highways.The scope of GLR is limited to geographic locations on the Earth's surface for the above-mentioned rationale.
