| Abstract | In Big Data era, it is difficult to build effecive intelligient analysis and decision support system as urban computing information resources are incomplete and the horizontal integration and contribution of information is seriously inadequate. Intelligient analysis and decision support system largely depends on the seamless connection of data fusion analysis and information presentation with real scenes. This paper presents the major issues that urban computing is facing. It analyzes three key technologies of urban computing in big data era, namely, the 3D spatial-temporal expression and establishment of urban scenes, the semantic computing and fusion of urban multi-modal data, and the on-the-spot analysis and decision-making of urban events. |
