Design and Implementation of Comprehensive Information Query and Analysis System Based on BIM+GIS
At present,most large-scale water conservancy projects have high information complexity and a large amount of data,and the relevant information cannot be obtained in time and effectively during decision analysis,so the management of water conservancy projects needs to be upgraded urgently.Starting from the requirements of digitalization,networking and intelligence in the construction of digital twin water conservancy,an information integration model is constructed to integrate BIM and GIS data,and a dynamic model generation and method based on time series is proposed.The method of lightweight and rendering of large-scale data is improved,BIM data is transformed,and the interoperability between BIM and GIS is realized,so as to dynamically render the three-dimensional model of the project.Finally,BIM parametric modeling,GIS data multivariate fusion and BIM+GIS fusion are introduced into the comprehensive information query and analysis system.Taking the project of diverting water from Chuo to Liaoning as an example,the efficient query and visual management of water conservancy project information are realized,which provides strong support for project decision-making and provides reference for comprehensive information management of other projects.
