标准范围

ISO 19115-2:2009通过定义描述图像和网格数据所需的模式，扩展了现有的地理元数据标准。它提供了有关用于获取数据的测量设备的特性、设备使用的测量过程的几何结构以及用于将原始数据数字化的生产过程的信息。该扩展涉及描述从原始数据推导地理信息所需的元数据，包括测量系统的属性，以及推导中使用的数值方法和计算程序。ISO 19115的一般部分充分说明了处理覆盖率数据所需的元数据。

ISO 19115-2:2009 extends the existing geographic metadata standard by defining the schema required for describing imagery and gridded data. It provides information about the properties of the measuring equipment used to acquire the data, the geometry of the measuring process employed by the equipment, and the production process used to digitize the raw data. This extension deals with metadata needed to describe the derivation of geographic information from raw data, including the properties of the measuring system, and the numerical methods and computational procedures used in the derivation. The metadata required to address coverage data in general is addressed sufficiently in the general part of ISO 19115.
