大学生活动时空模型的建立

Space-time Model Building of College Students' Activity

针对大学生的动态时空分布表示和可视化查询,建立了一个在GIS环境下面向行为的时空数据模型。该模型能够分别基于学生、时间和位置进行查询。以华中师范大学为例,将基于模型的原型系统在ArcGIS软件平台上予以实现和检验。结果显示,该模型的构建是极具利用价值的。

According to the purpose of dynamic temporal and spatial distribution and visual query of college students,this paper established a behavior-oriented space-time data model in GIS environment.The model could query based on the students,time and location.Taking the Central China Normal University for example,the system was realized and tested in ArcGIS software platform.The results show that it is extremely value to build the space-time model.
