传统空间数据库全覆盖式更新方法存在数据冗余及更新速率慢等问题,为了能够更好地支持海量城市三维数据的组织和更新工作,本文提出了一种基于道路格网的城市三维数据增量更新方法。利用城市道路格网分组、分块的特性进行城市三维数据的空间划分,建立城市格网模型,以不规则格网的形式进行城市三维数据的组织。利用城市格网模型划分的城市地理块具有不同功能属性的特点,以地理块的形式进行"时间+空间"的增量数据组织。可对城市三维数据进行时间方向和空间方向的历史回溯,改变了传统增量更新的查询管理方式。最后本文基于多基态修正模型设计了增量数据存储模型并给出了更新流程。以某市为例,开发了城市三维数据库增量更新原型系统,实现了城市三维数据的增量更新。 相似文献

空间数据具有空间位置、非结构化、空间关系,以及海量数据等特征。因此,对空间数据的存取性能,成为评价地理空间数据库极其重要的指标之一。BeyonDB是在国家"863"项目支持下研发的具有自主知识产权的地理空间数据库系统。目前,国内还没有支持地理空间数据库性能对比测试的工具软件,因此,为客观衡量BeyonDB的性能指标,有必要研发一种地理空间数据库性能对比测试的软件。本文分析了地理空间数据库性能对比测试软件的功能目标,采用面向对象的设计思想及方法,合理使用软件设计模式,进行了软件的总体框架与主控、功能命令、空间数据访问,以及测试结果输出等关键类的详细设计。介绍了实现该软件功能的方法、开发工具,以及主界面、文档输出界面等。最后,对软件的设计研发工作予以总结,提出今后的研究重点。 相似文献
