摘要
虚拟3D城市模型是三维城市GIS研究的基础。本文对CityGML1.0(City Geography Markup Language1.0,城市地理标记语言)的发展和核心技术进行了深入的研究,其主要内容包含了CityGML1.0的5层LOD模型、空间数据模型、CityGML模块、应用领域扩展等,还给出了基于CityGML1.0开发的系统实例,最后对CityGML的应用和发展进行了预测。
Virtual 3D city models is the foundation of the research of 3D city GIS. This paper deeply researches the development and the main technology of CityGML1.0, which mainly contains five LOD models, spatial data model, CityGML modules, application domain extensions （ADE） and etc. It also gives the example system based on CityGML1.0. Finally this paper forecasts the application and the development of CityGML.
