基于GIS语义的城市专题地理数据模型设计

摘要

分析了地理信息分类学在地理数据模型设计中的应用缺陷。为了有效解决专题数据共享与复用问题，笔者将GIS语义数据模型设计方法引入应用于城市专题数据模型设计中，并以城市绿地专题数据模型为例进行实践验证。%This paper analyzes the shortcoming of the application of geographic information taxonomy in geographic data model design .The author applies GIS semantics design method in the urban subject GIS data model to resolve the problem of data share and being used in multi-purpose , and validates the method in the urban greenbelt subject data model.
