Abstract:Pinglu Canal project construction scale is huge,involving many specialties,integration and coordination are difficult.On the basis of the canal waterway route demonstration,plane layout optimization and other key content,applications of building information modeling(BIM),geographic information system(GIS),oblique photography and other digital technology means in the project planning stage are explored.In addition,some technical difficulties such as multi-scale and multi-precision data matching and coordinate system transformation of spatial data are studied,and multi-source data fusion and information model construction are realized.At the same time,the application of the digital technology is dug deep into the planning scheme selection,information integration browsing,simulation,virtual roaming etc,and project pre-stage decision optimization and quality effect are assigned.
