摘要
目前,很多单位和高校都在进行区域三维地图的建设,数字化的三维地图不仅可应用于建设和施工规划,也可应用于生活实践、地理信息分析等方面。本文以某大学新建校区为例,基于Google Earth的GIS平台搭建由全站仪施测、以AutoCAD和SketchUp制作的三维校园BIM模型,再利用MFC和COM API技术进行程序封装和基于C/S的软件开发,制作出一个可移植的区域三维地图导览系统。该系统不仅可以实现基本地物的三维展示和自由漫游,也可以实现查询、路径导航等一系列GIS分析功能。
At present,many department and universities are carrying out the construction of 3 D virtual maps,three-dimensional maps can be used in the construction planning,classroom teaching,student practice and so on. In this paper,we use Hefei University of Technology Emerald Lake campus as an example,put the campus＇ s three-dimensional building information model,which made by Auto CAD and Sketch Up,in the Google Earth＇s GIS platform. And then use MFC and COM API technology for program packaging and secondary development,to produce a Three-dimensional of digital campus tour system based on C/S. In this system,not only can achieve three-dimensional display of the campus basic feature and roam in the campus freely,you can also query any place,gain route guidance and use a series of GIS analysis functions.
