标准摘要
[中文适用范围]： 地理数据库的上下文，旨在用于在编码器系统和解码器端定位与传输相关的现象。 本文档定义了此类对象的含义，并详细描述了引用，包括引用的组件是强制的还是可选的，以及它们的特性。 — 预编码LRM（预编码配置文件）； ——动态LRM（动态剖面）； ——精确相对 LRM（精确相对轮廓）。 定义了物理格式的要求。 将在软件、硬件或过程中实现。 本文件规定了以下与 LRM 相关的一般主题： ——LRM 的要求； ——LRM的概念数据模型； ——库存 LRM（见附件 A）。 本文件还提供： ——概念模型使用示例（见附件 B）； ——定义与 ISO/TC 211 的比较（见附录 C）。 [外文原描述]： The ISO 17572 series specifies location referencing methods (LRMs) that describe locations in the context of geographic databases and that are intended for use in locating transport-related phenomena both in an encoder system and from the decoder side. This document defines what is meant by such objects and describes the reference in detail, including whether or not components of the reference are mandatory or optional, and their characteristics. The ISO 17572 series specifies three different LRMs: — pre-coded LRM (pre-coded profile); — dynamic LRM (dynamic profile); — precise relative LRM (precise relative profile). The ISO 17572 series does not define a physical format for implementing the LRM. However, the requirements for physical formats are defined. The ISO 17572 series does not define details of the location referencing system (LRS), i.e. how the LRMs are to be implemented in software, hardware or processes. This document specifies the following general LRM-related subjects: — requirements of an LRM; — conceptual data model for LRMs; — inventory LRMs (see Annex A). This document also provides: — examples of conceptual model use (see Annex B); — a comparison of definitions with ISO/TC 211 (see Annex C).
