摘要
针对决策支持系统中空间数据可视化应用趋势,研究基于空间数据仓库的一种决策分析工具———在线分析处理,通过改进空间数据立方体的物化视图选择方法,并进行了实例分析,验证该方法的有效性和优越性,更好地解决空间OLAP响应时间延迟问题.进而扩展空间OLAP应用模型和模式,实现更加完备、灵活的空间OLAP操作功能.
There now appears urgent need for embedding spatial data into decision support system(DSS) which provides spatial analytical function and visualization to user. This article investigates a decision analytical tool based on spatial data warehouse-Online analytical processing(OLAP). We mainly solve the serious problem of slow response time in spatial data cube operation by improving materialization view selection method. And then, an analysis example is given to test the efficiency of our work. Furthermore we enrich the spatial OLAP model and its application mode to realized more powerful and flexible spatial analytical functions.
