摘要
"数字城市"是城市新的增长点,这一概念的提出源于"数字地球",是城市化进程加快、可持续发展的必然要求。Skyline是当前世界应用较为广泛的3维软件之一,它能够快速地融合数据,更新场景数据库,展现3维地理空间数据,功能强大。文章探讨并实现了通过收集资料、数据预处理、建立3维地形空间数据库、快速3维建模、空间数据整合、系统集成等一系列步骤建立起的基于Skyline、以辽宁省某市景观带为项目区的3维漫游系统关键技术。
Digital City, which comes from the concepl of digital earth, is a new economic growth point of city development and the necessary requirement of expediting urbanization and sustainable development. Skyline, which is able to fuse data, update scene database and display 3D topographical spatial data without delay, is a kind of powerful 3D software widely used in the world. This paper discusses and realizes some key techniques of constructing 3D roaming system using the landscape belt of a certain city of Liaoning Province as the project area through a series of steps including information collection, data pre -processing,3D topographical spatial database construction,quick 3D modeling,spatial data fiJsion and system integration.
