摘　　要：大规模三维城市模型在城市规划与管理、环境模拟、应急响应、导航、虚拟旅游以及其他科学和大众应用方面的需求越来越高。在过去的20年中,通过多学科的共同努力,大规模城市三维建模已经取得了可观的成就。本文全面总结和讨论了三维城市建模在数据源、建模方法和平台、模型表达和互操作等方面的新技术和新进展,并描述了世界范围内开放城市模型的几个代表性示例。在日益多样化的数据,先进但价格可承受的技术以及不断增长的公共和科学需求的推动下,三维城市建模正在加速实现自动化、细致化、语义化、标准化、一体化和大众化。Large scale 3D city models become increasingly demanding for urban planning and management, environmental simulation, emergency response, navigation, virtual tourism and other scientific and public applications. Considerable achievements have been accomplished over the past two decades through joint efforts from multiple disciplines. The objective of this paper is to comprehensively summarize and discuss the current technologies and recent progresses of 3D city modeling in data sources, modeling methods and platforms, 3D city model representation and interoperability. Finally, several representative examples of open city models across the world are described. Driven by the increasing diverse data, advanced yet affordable technology, and growing public and scientific needs, 3D city modeling is accelerating to be automatic, meticulous, semantic, standardized, seamless, and open to the general public.
