空间数据模型是GIS实现空间数据组织、表达、分析、处理和应用的基础。从面向对象的角度提出了面向对象空间数据模型(OOSDM)的相关定义、对象构建过程、空间数据组织和管理模式,并以城市道路交通信息为例,设计了道路交通信息的对象组织方法和构建过程。模型设计方法的研究为空间数据库的建设和数据共建共享提供了新的方法和思路。 更多还原
【Abstract】 The spatial data model is the base of GIS data organization,expression,analysis,processing and application.Both related definition,construction method of the object and the organization and management model of the spatial data were presented from the point of object-oriented.Finally,urban road traffic information was taken as an example.And the object organization and construction process of that was designed.The research set up a way of constructing and sharing the spatial database. 更多还原
