三维城市地理信息可视化服务系统的设计与实现

三维城市地理信息可视化服务系统是一个建立在分布式数据管理与集成基础上的“一站式”空间信息服务平台,本文基于数字城市空间框架,通过对各类测绘成果数据进行管理、展示、应用,形成了三维城市地理信息可视化服务系统,研究了可视化服务系统的架构,按照公众版和专业版形成了不同的功能结构图,最后给出了系统效果。结果表明,三维城市地理信息可视化服务系统是建立面向公众、政府、行业、企业及社区的公共信息服务平台、信息应用系统的重要组成部分,能够为提高城市可持续发展以及规划、建设、管理和服务水平提供借鉴和参考作用。

Design and Implementation of 3D Urban Geographic Information Visualization Service System

The 3D Urban Geographic Information Visualization Service System is a“one-stop”spatial information service platform based on distributed data management and integration.Based on the digital urban spatial framework,this paper manages,displays,and applies all kinds of surveying and mapping data.It proposed a three-dimensional urban geographic information visualization service system,studied the architecture of the visual service system,discussed different functional structure diagrams according to the public version and the professional version,and finally presented the system effect.The results show that the 3D urban geographic information visualization service system is an important part of establishing public information service platforms and information application systems for the public,government,industry,enterprises,and communities,and provides references for improving urban sustainable development and planning,construction,management and service level.
