摘要
传统GIS只能实现简单的查询分析,提供空间位置和属性信息,呈现校园景象的静态图片,而不能实现动态表达。对校园植被进行时态空间表达,不仅能实现传统GIS功能,而且能实现对校园植被的动态表达。从时空数据库的构建着手,设计了专题符号库和时空表达模型,从而达到校园植被随时间变化而变化显示的目的。
The application of traditional GIS in campus vegetation is to achieve a simple query and analysis, and provide the spatial location and attribute information. So the campus scene is presented as static pictures, dynamic expression can't be achieved. The spatio-temporal expression of campus vegetation can not only solve the traditional GIS implementation function, but also realizes the dynamic expression of campus vegetation. We constructed the spatio-temporal database, designed a special symbol library, and described the spatio-temporal expression model in this paper.
