标准范围

ISO 19115:2003定义了描述地理信息和服务所需的模式。它提供了关于数字地理数据的识别、范围、质量、空间和时间模式、空间参考和分布的信息。ISO 19115:2003适用于:数据集的编目、信息交换所活动和数据集的完整描述；地理数据集、数据集系列以及单个地理特征和特征属性。ISO 19115:2003定义:强制和条件元数据部分、元数据实体和元数据元素；服务于所有元数据应用（数据发现、确定数据的使用适用性、数据访问、数据传输和数字数据的使用）所需的最小元数据集；可选元数据元素-如果需要，允许对地理数据进行更广泛的标准描述；一种扩展元数据以满足特殊需求的方法。虽然ISO 19115:2003适用于数字数据，但其原理可以扩展到许多其他形式的地理数据，如地图、图表和文本文档以及非地理数据。注意某些强制性元数据元素可能不适用于这些其他形式的数据。

ISO 19115:2003 defines the schema required for describing geographic information and services. It provides information about the identification, the extent, the quality, the spatial and temporal schema, spatial reference, and distribution of digital geographic data.ISO 19115:2003 is applicable to:

• the cataloguing of datasets, clearinghouse activities, and the full description of datasets;
• geographic datasets, dataset series, and individual geographic features and feature properties.

ISO 19115:2003 defines:

• mandatory and conditional metadata sections, metadata entities, and metadata elements;
• the minimum set of metadata required to serve the full range of metadata applications (data discovery, determining data fitness for use, data access, data transfer, and use of digital data);
• optional metadata elements - to allow for a more extensive standard description of geographic data, if required;
• a method for extending metadata to fit specialized needs.

Though ISO 19115:2003 is applicable to digital data, its principles can be extended to many other forms of geographic data such as maps, charts, and textual documents as well as non-geographic data.NOTE Certain mandatory metadata elements may not apply to these other forms of data.
