中文摘要:

瞄准综合管理和盖住一个城市的完整的 3D 空格的大规模 3D geospatial 信息的全面应用程序,这篇论文简短介绍完整的 3D 的设计和实现 GIS 站台:GeoScope,它为巨大的完整的三维的 geospatial 数据集成,管理,分析,可视化,和应用程序提供一个职业解决方案。GeoScope 旁边被描绘:(1 ) extendible 软件建筑学基于层次消息公共汽车,便于 2D GIS 和 3D GIS 的多模式的综合应用程序;(2 ) 统一了 3D 城市模型,支持室外与室内、未葬与地下的 3D 目标的多尺度的语义表示;(3 ) 高度有效的 3D geospatial 数据库引擎,为即时应用程序支持巨大的 3D geospatial 数据的综合管理;并且(4 ) 利用现代 GPU 的大规模平行的计算建筑学的高效的可视化引擎,支持大规模复杂 3D geospatial 环境的即时现实主义的显示。GeoScope 的成功的飞行员应用程序也与整个武汉城市的 8494 km2 的 3D 城市模型一起被说明,在中间的中国的最大的城市。

英文摘要:

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 se- mantic 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 modem 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 knl2 of the whole Wuhan City, the largest city in middle China.
