摘　　要：为实现大规模地形景观和精细工程设施模型在三维GIS中的无缝集成管理,并支持工程设施全生命周期的共享应用,提出了一种可根据设计参数自动建立复杂设施三维模型并交互式编辑修改的方法,扩展了三维GIS数据模型,实现了三维几何模型与其参数信息的有机集成与同步更新,并以桥梁模型的构建为例验证了该方法的可行性和有效性。Aiming to seamlessly integrate elaborated engineering facilities models and large scale land scape models as well as to support the sharing and application life cycle of three-dimensional GIS,wepropose a new method to automatically build complex models of engineering facilities using designed parameters. The traditional 3D GIS data model is extended to satisfy the demands for integration and synchronous updating of geometric models and their related parameters. Finally, the validity and fea- sibility of this method are demonstrated through its application for bridge modeling. The proposed method facilitates seamless integration of GIS and CAD.
