摘　　要：三维数据底板是流域数字化映射的成果,更是数字化场景构建、智慧化模拟迭代的基础。为厘清三维数据底板建设的技术逻辑,系统性地阐述了三维数据底板的定位、建设任务和技术路线图,重点对建设过程中的海量数据融合、数据轻量处理、场景渲染发布、数据可视可算、数据共享共建等关键技术问题展开深入全面的论述,分析技术难点、解决路径和具体方法。基于以上研究,以浙江省曹娥江数字孪生流域为例,运用BIM+GIS等技术构建L2、L3三维数据底板,以三维数字化场景支撑流域“四预”可视化模型应用。相关成果对类似数据底板建设具有借鉴意义。As a result of basin digital mapping,3D data baseboard is the basis of digital scene construction and intelligent simulation iteration.In order to clarify the technical logic,this article systematically elaborates on the positioning,construction tasks,and technical roadmap of the 3D data Baseboard.We elaborate key technologies such as massive data fusion,lightweight data processing,scene rendering and publishing,data visualization and calculation,and data sharing and co construction during the construction process,during which we focus on the technical difficulties,solutions,and specific methods.Based on the above research,taking Cao′e River digital twin basin as an example,we construct 3D data baseboard(L2 and L3)based on BIM+GIS and other technologies,and use 3D digital scenes to support the application of visualization models such as"four presets"in the basin.The results have reference significance for similar data baseboard construction.
