三维数字城市建筑物实时动态查询系统的设计与实现

三维建筑物实时动态查询系统的建立是三维数字城市系统空间信息基础设施建设的重要组成部分.本文利用C#平台结合Skyline二次开发工具,以吉林市为例,开发实现了大范围城市建筑物信息的实时查询.该系统既实现了三维信息浏览、编辑、修改、统计分析、显示和查询等功能,又提供了较高的三维可视化效果.

TheDesignandRealizationofaReal-Timeand DynamicInquirySystemoftheBuildingsin3DDigitalCities

The establishment of the real-time and dynamic inquiry system of three-dimensional buildings is the crucial part of the infrastructure construction for the 3D-digital-city system’s spatial information.Based on C# and Skyline-the secondary development tool,and with Jilin city as an example,the authors of this article have developed a real-time and dynamic inquiry system to inquire the information of large-scale city buildings.The system not only realizes the functions of 3D information browsing,editing,amending,statistic analysis,displaying and inquiring,but also provides accurate 3D view data.
