基于 SketchUp 和 ArcGIS 的三维校园建模方法应用

摘要

数字校园已经成为数字城市建设的核心内容之一，其主要是利用地理空间信息技术整合数字化校园内的教学、科研和学生生活、学习服务信息，以达到信息和资源的共享，促进学校制度的创新、管理的创新。以昆明冶金高等专科学校安宁校区为研究对象，基于 cass 数字测图技术并结合 SkectchUp 建模技术和利用 ArcGIS 地理空间信息技术软件为平台，构建三维数字校园系统，实现数字校园的三维虚拟模型。对于不同地物使用不同建模方式，并对构建模型进行属性信息的添加，实现了在 ArcGIS 软件平台上进行空间数据的访问、流畅三维校园漫游和查询三维数字校园信息。%Digital campus has become one of the most important content of digital city construction.In order to achieve information and resource sharing and to promote college education system and daily edu-cation management innovation,it uses geographic space information technology to integrate teaching and research,student life and learning service information,other digital information and resources in digital campus.This paper takes Kunming Metallurgy College Anning campus as research object,using ArcGIS geographic space information technology software as the platform and combining gass digital mapping tech-nology and SketchUp modeling technology to establish three-dimensional digital campus system,which re-alized three-dimensional virtual digital campus model.As to different object that has different data type, so it proposed different modeling methods.After that,it also adds attributes information to construct three-dimensional model.Finally it realized spatial data access,smooth three-dimensional digital campus roaming and three-dimensional campus information inquiring.
