摘要：Modern urban infrastructure needs a comprehensive and integrated information science and technology. Global Position System (GPS), Geographic Information System (GIS), Digital Photogrammetry and Remote Sensing (RS) and other spatial information technologies are it's core techniques. Products of digital photogrammetry and remote sensing are its basic information resource. The key tasks of modern urban infrastructure are urban planning and management, city modeling and constructing digital city. Urban planners and administrators use UGIS and RS Technologies both as a spatial database and an analysis and modeling tool. This paper presents the use of UGIS in the urban planning and management, and the application of 4D and relevant technologies for modern urban infrastructure. It contains four sections. Firstly, the contents of modern urban infrastructure are introduced. Some advanced technologies such as 3D city model and cybercity with virtual reality (VR) environment for UGIS are outlined. Secondly, traditional urban planning and management bases on 2D. Problems during the existing planning process arise because of lack of 3D functionalities to analyze and visualize the 2D/3D data. However, 4D techniques are information of resources of creating and analyzing 3D city model. Three dimensional digital urban model and cybercity constructed using DEM,DOM and associate techniques are present. Thirdly, an example of application of integration of UGIS and digital photogrammetry and remote sensing in urban transportation is explored. Finally, some conclusions are made
