Research on Application of BIM+GIS Technology in 3D Visualization of Urban Architecture
Taking a project as an example,this paper obtains a lightweight BIM model by combining geometric transformation and rendering processing.The lightweight model is imported into the 3D visual display platform,and the hierarchical and classified display of BIM model is realized by triggering the layer height attribute of the BIM model of the system according to the spatial elevation attribute information corresponding to the component.By using 3GIS technology and combining the corresponding correlation,the geography-thing correlation and the mixed correlation,the attribute data in the geographic information is combined with the vectorized or raster data to form a set of GIS geographic data that can be applied.On the basis of urban space visualization,urban construction data is integrated to form a basic database of urban construction,which lays data support for building a new system of smart city construction,operation,maintenance and management with"city visualization,management refinement,resource sharing,data opening,and service convenience".
