基于GIS技术的三维可视化数字校园建设研究——以贵州大学为例

“数字化校园”通过对校区内地物地貌进行数字化建模,形成可视的校园基础地理信息模型,具有覆盖面积小、资料容易获取、实地踏勘方便等优势,对于现代化校园建设管理具有积极意义。通过高清卫星影像图与实地调查相结合的方法,进行了ArcGIS区域矢量化、三维建模以及编写HTML网页的工作,实现了三维可视化校园成果在ArcScene平台和网页平台的展示。结果表明,利用SketchUp建模并通过网页浏览的效果较好,普适性更强,更易被大众所接受,拓宽了三维可视化成果的受众范围。

Research on 3D Visual Digital Campus Construction Based on GIS Technology: Taking Guizhou University as an Example

"Digital Campus"forms a visible campus basic geographic information model by digitally modeling the geomorphology of the campus.It has the advantages of small coverage area,easy access to data,and convenient field surveys.It has positive significance for modern campus construction management.Through the combination of high-resolution satellite image maps and field surveys,the work of vectorizing,3D modeling,and programming HTML pages of ArcGIS regions was carried out,and the 3D visualization of campus results was displayed on the ArcScene platform and web platform.The results show that modeling with SketchUp and browsing through web pages have better effects,are more universal,and are more easily accepted by the general public,which broaden the audience of 3D visualization results.
