基于数码技术的大比例尺城市三维景观虚拟现实技术

The Imaginary-reality Technology of Large Scale City Landscape of 3 Dimension Basing on Digital Code

作为数码城市（ＣｙｂｅｒＣｉｔｙ）最重要内容的城市三维景观虚拟现实作为一门新兴的ＧＩＳ技术其应用极为广泛。本文结合课题实际应用在阐述了城市三维景观虚拟现实的模型构建、系统集成的基础上。利用ＤＥ Ｍ、ＤＯＭ、ＤＬＧ基础数据、三维可视地理信息系统软件平台，提出了一套完整的城市三维景观虚拟现实研制的技术路线，在实际科研中证明是可行的。

The city three dimensional imaginary-reality being the important content of cybercity is a new GIS technology,its application is very wide. In the base of mentioning the model making,system integration of city three dimensional imaginary- reality, A whole technology line of making city three dimensional imaginary-reality is proposed, which uses the basic data such as DEM .DOM .DLG and three dimensional visual geographical information platform.
