ISO 19125-1:2004建立了地理信息的通用体系结构，并定义了体系结构中使用的术语。它还标准化了几何图形类型的名称和几何图形定义。 ISO 19125-1:2004没有对如何定义内部模式中的几何类型提出任何要求，也没有对何时、如何或谁定义几何类型提出任何要求。ISO 19125-1:2004不试图标准化，也不依赖于添加和维护类型的机制的任何部分。

ISO 19125-1:2004 establishes a common architecture for geographic information and defines terms to use within the architecture. It also standardizes names and geometric definitions for Types for Geometry. ISO 19125-1:2004 does not place any requirements on how to define the Geometry Types in the internal schema nor does it place any requirements on when or how or who defines the Geometry Types. ISO 19125-1:2004 does not attempt to standardize and does not depend upon any part of the mechanism by which Types are added and maintained.
