摘要
在现今万物互联、虚实交融的背景下,全世界都在探索城市智能运行持续创新的前沿模式和未来发展形态。城市地理信息数据作为与国家安全和社会经济发展密切相关的基础战略信息资源,也是数字孪生城市的重要组成部分,其准确性和时效性有着至关重要的作用。首先,立足政策和环境、机制和技术的角度,总结了面向数字孪生城市的城市地理信息更新的历史与现状;其次,从变化发现的渠道和机制、变化的种类和区域、更新方案和技术方法3个方面探讨了数据更新的关键问题;最后,对城市地理信息高效更新的应用前景进行了展望。
Under the background that all things are connected and the physical world is combined with digital technology,the whole world is searching for an advanced and forwardlooking city development mode with smart operation and continuous innovations.Urban geographic information is a kind of basic and strategic information resource related to national security and social and economic development,also an impor tant part of digital twin cities,whose accuracy and timeliness are of great significance.First,the renewing history and current situation of urban geographic information facing digital twin cities related to policy,environment,technology and mechanism are summarized.Then,the key problems of data renewal are investigated from three aspects:channels and mechanisms of change discovery,types and regions of change,renewal schemes and related technical methods.Finally,the application of efficient renewal of urban geographic information is prospected.
