城市空间数据基础设施研究

Research on Urban Spatial Data Infrastructure

城市空间数据基础设施(USDI)是"数字城市"建设的关键环节,该文分析了城市地理空间数据的应用特点及目前地理空间数据共享存在的问题,围绕地理空间数据共享与互操作,从机构体系、空间数据资源、政策法规与标准体系、数据交换与服务体系等方面,对城市空间数据基础设施进行研究。

Construction of USDI is the key to the development of 'Digital City'. In this paper, a research on USDI has been undertaken, focusing on geo-data sharing and interoperation, on the view of administrative setup,spatial-data resource system, policy and standardization system, on the basis of analysis of data application characteristic and existing problem of data sharing.
