Construction of Multi-scale 3D Data Base Plate for Digital Twin Watershed
[Purposes]Data base plate is the first task of the construction of digital twinning related proj-ects,and the"cornerstone"of the realization of the"four pre-projects"of digital twinning watershed.[Methods]According to the smart water conservancy implementation plan of the Ministry of Water Re-sources of the People's Republic of China and the information requirements of the basin,this paper pro-poses a multi-scale three-dimensional digital baseboard construction scheme based on geospatial data,defines the goal of three-dimensional scene data baseboard construction,and puts forward the specific way of multi-source and multi-scale digital twin baseboard data construction.The theory and method of data source,data acquisition,data governance and data fusion are expounded in the process of floor con-struction.[Findings]Through practice,the construction content and technical route of L1-L3 data back-board are refined,and the complete idea and method of digital twin project data backboard construction are given.[Conclusions]Through the construction and sharing of the three-level floor,the high-precision visual scene is constructed,which can provide strong data support for business applications such as intelligent flood prevention,water resources management and deployment.
