本文档指定了用于描述地理实体的空间特征的概念模式,以及与这些模式一致的一组空间操作。它处理“向量”几何和拓扑。它定义了用于空间(几何和拓扑)对象地理信息的访问、查询、管理、处理和数据交换的标准空间操作。由于地理信息的性质,这些几何坐标空间通常最多有三个空间维度、一个时间维度和应用程序所需的任意数量的其他空间相关参数。一般来说,几何对象的空间投影的拓扑维数最多为三。

This document specifies conceptual schemas for describing the spatial characteristics of geographic entities, and a set of spatial operations consistent with these schemas. It treats "vector" geometry and topology. It defines standard spatial operations for use in access, query, management, processing and data exchange of geographic information for spatial (geometric and topological) objects. Because of the nature of geographic information, these geometric coordinate spaces will normally have up to three spatial dimensions, one temporal dimension and any number of other spatially dependent parameters as needed by the applications. In general, the topological dimension of the spatial projections of the geometric objects will be at most three.
