摘要： 针对常用的WGS-84坐标系统，应用基于统一建模语言(UML)的面向对象建模方法，建立空间位置和坐标变换的对象模型，采用UML类图描述空间参考坐标系模型、空间位置模型和坐标变换模型的对象定义、层次结构和关联关系，采用UML活动图和顺序图描述坐标变换算法。

Abstract: Focusing on the widely-used WGS-84 reference frame, this paper presents the object model of spatial reference frame, spatial position, and coordinate conversion, using the UML-based object-oriented modeling paradigm. The UML class diagram is used to visualize the object definitions, hierarchies, and associations of the models. The UML activity diagram and sequence diagram are used to describe the algorithms of coordinate conversions.
Key words:
WGS-84 reference frame,
coordinate conversion,
object-oriented modeling
