摘要:

以航空影像、卫星影像、数字高程模型和相关专题数据为数据源,利用Skyline软件完成甘肃省政务地理信息平台的三维场景建设,重点阐述了在海量数据前提下,运用多CPU协同计算的方式构建三维地形模型的流程和方法,最后通过案例介绍了平台三维系统的应用方向和价值。

关键词: 三维地理信息系统地形建模Skyline    
Abstract:

This paper introduces the method and process of 3D GIS system creation in skyline software environment.The data source of the 3D GIS system includes aerial and satellite images,digital elevation model data and related thematic data.All these data come from Gansu Political GIS platform; meanwhile,the 3D system is an indispensable part of this platform.Because 3D terrain model is the foundation of 3D GIS system,also,3D terrain model uses mass data,which leads to many problems,so,some important issues and experiential parameters during 3D terrain model creation based on mass data is presented in this paper.Multi-computer cooperating calculating is used in the procedure.Last but not the least,application instances of the 3D GIS system in Gansu province is illustrated.

Key words: 3D GIS    Terrain model creation    Skyline
