Application and Exploration of BIM+GIS in Island Project Survey and Analysis
The article takes the Yantai Kongtong project as the carrier and is based on the practice of island projects.By integrating BIM and GIS technology,ContextCapture software is used to construct a 3D GIS scene for unmanned aerial vehicle technology data collection.The OSGB and UDBX standards,which are representative of BIM and GIS,are selected in the data exchange format.Through preprocessing of various model data in Revit and 3dMaxs modeling software,the BIM model as the data source is imported into a GIS platform that can display large-scale space.With accurate oblique photography models and map geographic information,a 3D visualization scene and a characteristic island survey and design system with a fusion error of only centimeters between BIM and GIS data are established based on the SuperMap geographic information platform,which is an excellent survey and design system.Design and construction management lay the foundation.
