This paper aims to create a new searchable 3D city model to help managers improve their decision-making.,This paper identifies data management basics and the key elements used in the new model design; it further analyzes five-city models, presents its findings and proposes analytical trends for the new model. It discusses the concepts underlying existing models, explains the benefit brought by the proposed model and demonstrates its robustness.,City systems can be interconnected, thanks to data digitization and the integration of new technologies into different management processes. Although there are several 3D city models available, none of those identified in this research can be queried for several sectors.,This model design can only be successfully realized in the presence of a public mandate. Potential limitations include information security risks and political non-acceptance.,The present work proposes a searchable and high performance model having the distinctive capacity to bring together city systems and perform real-time data analysis in order to extract important information needed to guide the city, and in the context of a global vision.

致力于创建可搜索的3D智能城市模型

本文旨在创建一个新的可搜索3D城市模型，以帮助管理人员改善决策。本文确定了数据管理的基础知识和在新模型设计中使用的关键元素；它进一步分析了五城市模型，介绍了其发现并提出了新模型的分析趋势。它讨论了现有模型的基本概念，解释了所提出模型带来的好处并展示了其健壮性。由于数据数字化以及将新技术集成到不同的管理过程中，城市系统可以相互连接。尽管有几种可用的3D城市模型，但在本研究中确定的模型都无法在多个部门中查询。只有在有公共任务授权的情况下，才能成功实现此模型设计。
