标准摘要
[中文适用范围]: 该国际标准规定了位置参考方法(LRM),该方法描述地理数据库上下文中的位置,并将用于定位编码器系统以及解码器端中与传输相关的现象。 本国际标准定义了此类对象的含义,并详细描述了参考,包括参考的组成部分是强制性的还是可选的,以及它们的特征。 本国际标准规定了两种不同的 LRM: ——预编码位置参考(预编码配置文件); ——动态位置参考(动态配置文件)。 本国际标准没有定义用于实施 LRM 的物理格式。 但是,定义了物理格式的要求。 本国际标准没有定义位置参考系统(LRS)的细节,即如何在软件、硬件或过程中实现 LRM。 ISO 17572 的本部分规定了动态位置参考方法,包括 — 属性和编码规则 — 逻辑数据建模 — 动态位置参考的 TPEG 物理格式规范, — 动态位置参考的编码指南; ——压缩数据格式规范。 它与 ISO/TC 204 制定的其他国际标准(例如 ISO 14825)一致。 [外文原描述]: The ISO 17572 series specifies location referencing methods (LRMs) that describe locations in the context of geographic databases and will be used to locate transport-related phenomena in an encoder system as well as in the decoder side. The ISO 17572 series 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 two different LRMs: -pre-coded location references (pre-coded profile); -dynamic location references (dynamic profile). The ISO 17572 series does not define a physical format for implementing the LRM. However, the requirements for physical formats are defined. ISO 17572-3:2014 does not define details of the location referencing system (LRS), i.e. how the LRMs are to be implemented in software, hardware, or processes. ISO 17572-3:2014 specifies the dynamic location referencing method, comprising -attributes and encoding rules; -logical data modelling; -TPEG physical format specification for dynamic location references; -coding guidelines for dynamic location references; -compressed data format specification.
