Abstract:Three-dimensional GIS (3D GIS) is one of the primary and typical contents of GIS technology at pres-ent and in the future, which overcomes the constraints of representing 3D GIS spatial information in two-dimen-sional map, as well as provides a more effective decision-making support for people’s daily life. This paper fo-cuses on the research progress and its key technologies of 3D GIS, including the data model, database manage-ment 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 im-provement of city management. Finally, the applications of 3D GIS for spatio-temporal information bearing en-gine and spatial intelligence in smart city and city safety are investigated.
Keywords:三维GIS  three-dimensional GIS  three-dimensional visualization  three-dimensional spatial analysis  bearing engine  smart city
