Abstract: Based on the study of the conventional spatial data structure and data model,this paper brings forward a data model with Objected-Oriented organization mode and discusses spatial data organization,the structure of Infrastructure Objects,O/R mapping mode.Via using this model,it is better for the upper-layer software to adopt objected -oriented design and implementation.

Key words: Objected-Oriented, data model, GIS

摘要: 在对传统的空间数据结构和数据模型研究的基础上,提出了一种以面向对象的方式组织的数据模型,并针对GIS数据的组织、底层对象的结构、O/R映射方式进行了讨论。通过使用这种模型,更有利于在上层软件中采用面向对象的设计和实现。
