Abstract: The paper takes advantage of OO theory,refers to international data model specification,and presents the tri-model theory including Spatial Object Model,Geometry Object Model and Geometry Graph Object Model.The mentioned theory is on the base of GML specification.The method which making use of geometry schema and feature schema offered by GML,for describing Spatial Object Model and Geometry Model has been explained,together with another method which takes SVG as Geometry Graph Object model.

摘要: 作者根据面向对象的理论,参照国际技术规范,提出了几何对象模型、地理对象模型、图形对象模型构成的三层数据模型。并利用GML提供的几何模式、特征模式对地理对象模型和几何对象模型进行了描述,采用SVG作为几何图形显示模型的描述。
