ISO 19111:2007定义了通过坐标描述空间参照的概念模式，可以选择扩展到时空参照。它描述了定义一维、二维和三维空间坐标参考系所需的最少数据，并扩展到合并的时空参考系。它允许提供额外的描述性信息。它还描述了将坐标从一个坐标参考系更改为另一个坐标参考系所需的信息。在ISO 19111:2007中，坐标参考系不随时间变化。对于在汽车、船舶、飞机和航天器等移动平台上定义的坐标参考系，到地球固定坐标参考系的转换可以包括时间元素。ISO 19111:2007适用于地理信息的生产者和用户。虽然它适用于数字地理数据，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。所描述的模式可应用于水平位置与第三个非空间参数的组合，该参数随高度或深度单调变化。这种对非空间数据的扩展超出了ISO 19111:2007的范围，但可以通过配置文件实现。

ISO 19111:2007 defines the conceptual schema for the description of spatial referencing by coordinates, optionally extended to spatio-temporal referencing. It describes the minimum data required to define one-, two- and three-dimensional spatial coordinate reference systems with an extension to merged spatial-temporal reference systems. It allows additional descriptive information to be provided. It also describes the information required to change coordinates from one coordinate reference system to another.In ISO 19111:2007, a coordinate reference system does not change with time. For coordinate reference systems defined on moving platforms such as cars, ships, aircraft and spacecraft, the transformation to an Earth-fixed coordinate reference system can include a time element.ISO 19111:2007 is applicable to producers and users of geographic information. Although it is applicable to digital geographic data, its principles can be extended to many other forms of geographic data such as maps, charts and text documents.The schema described can be applied to the combination of horizontal position with a third non-spatial parameter which varies monotonically with height or depth. This extension to non-spatial data is beyond the scope of ISO 19111:2007 but can be implemented through profiles.
