改进可重用性三维(3D ) 当模特儿并且简化自然景色重建的复杂性，这份报纸为通用 3D GIS 论述一个 3D 模型数据库。在它的可扩展的功能建筑学的介绍以后，在 3D GIS 的任何重建的景色由模型的含蓄的空间时间的层次的结论伴随了为通用，几个关键问题详细被讨论例如 3D 模型和相关检索和负担方法的存储和管理，象为进一步按需的开发的接口一样。最后，这个模型数据库的有效性和可行性在铁路操作的 3D 可视化系统的开发通过它的应用程序被证明。
Aiming at the integrative management and comprehensive applications of large-scale 3D geospatial information covering the full 3D space of a city,this paper briefly introduces the design and implementation of a full 3D GIS platform:GeoScope,which provides a professional solution for the massive full three-dimensional geospatial data integration,management,analysis,visualization,and applications.GeoScope is characterized by:(1) extendible software architecture based on the hierarchical message bus,facilitates multimodal integrative applications of 2D GIS and 3D GIS;(2) unified 3D city models,support multiscale semantic representation of outdoor & indoor and aboveground & underground 3D objects;(3) high-efficient 3D geospatial database engine,supports integrated management of massive 3D geospatial data for real-time applications;and (4) high-performance visualization engine exploiting the massively parallel computation architecture of modern GPUs,supports real-time realistic rendering of large-scale complicated 3D geospatial environments.The successful pilot application of GeoScope is also illustrated with the 3D city models of 8494 km2 of the whole Wuhan City,the largest city in middle China.
我们与空间数据交往的方法从 2D 地图被改变了到 3D 虚拟地理环境(VGE ) 。当 VGE，和特别地 3D 城市模型提供一个有效方法在城市的区域集成巨大的、异质的 geospatial 信息和 georeferenced 信息，一台计算机上的地理信息的三维的代表被知道。(3DCM ) 3D 城市建模是在不同申请区域的一个活跃研究和实践话题。这篇论文介绍在 3D GIS，虚拟环境，和 AEC/FM 采用的不同当模特儿的范例。新 3DCM 技术正在演变为数据集成和合作途径代表一个城市的完整的空间范围，到未葬、地下的模型，室外、室内的环境包括人造有 3D 几何学，外观，拓扑学和语义的目标和自然特征。
