摘要:

三维GIS是当今乃至未来GIS技术的主要标志性内容之一,它突破了空间信息在二维地图平面中单调表现的束缚,为各行各业以及人们的日常生活提供了更有效的辅助决策支持。本文重点介绍了三维GIS的数据模型、数据库管理和可视化分析等关键技术及其研究进展,并以武汉市为例展示了三维GIS对城市立体空间的整体表达,为大城市、全市域的三维数字城市建设奠定了基础,最后探讨了在智慧城市建设与城市安全中三维GIS将发挥日益重要的时空信息承载引擎与空间智能技术支撑作用。

Abstract:

Three-dimensional GIS (3D GIS) is one of the primary and typical contents of GIS technology at present and in the future, which overcomes the constraints of representing 3D GIS spatial information in two-dimensional map, as well as provides a more effective decision-making support for people's daily life. This paper focuses on the research progress and its key technologies of 3D GIS, including the data model, database management and visual analysis. The pilot applications of 3D GIS in Wuhan are also illustrated. The entire 3D space of the city is represented by 3D GIS. Then construction of the large-scale city digitalization is enabled with the improvement of city management. Finally, the applications of 3D GIS for spatio-temporal information bearing engine and spatial intelligence in smart city and city safety are investigated.

Key words: three-dimensional GIS, three-dimensional spatial analysis, bearing engine, three-dimensional visualization, smart city
