面向城市管理的地理实体服务方法研究与应用

Research and application of geo-entity service method for urban management

针对传统地图服务展示单一、信息固定,无法全面表达地理实体的多维度信息的局限,在深入分析地理实体特点的基础上,该文提出了一种“类血缘关系”地理实体服务与可视化方法,搭建面向城市服务的多表多维存储结构设计、模拟血缘关系构建地理实体检索与可视化方法,形成了集查询、检索和显示一体的全套解决方案,实现对地理实体的多角度展示和灵活扩展。基于上海国土信息平台的应用实验结果表明,该文设计的方法可以支持用户按需选择空间形态,灵活支撑各类融合信息的显示,进一步可按需组装提取用户所需作为信息分析和挖掘的基础。

Traditional map services display single and fixed information,and cannot fully express multi-dimensional information of geo-entities.According to this situation,this paper proposed a“simulating blood relationship”geo-entity serving and visualization method,based on the in-depth analysis of the characteristics of geo-entities.This method formed a complete set of solutions integrating query,retrieval and display.It realized multi-angle display and flexible expansion of geographical entities by building a multi-table and multi-dimensional storage structure design for urban services,and a retrieval and visualization method for geographical entities simulating kinship.The application experiment results based on the Shanghai Land Information Platform showed that the method designed in this paper could support users to select the spatial form according to their needs,flexibly supported the display of various fusion information,and further could assemble and extract users’needs as the basis of information analysis and mining.
