Design and Implementation of an Indoor and Outdoor 3D Integrated System Based on BIM+GIS
The traditional virtual scene is built based on a 3D GIS platform,and it focuses on the organization and invocation of massive terrain data,the description of multi-resolution terrain and the integration of multi-source data,mainly expresses the outdoor terrain environment from a macro perspective,but lacks the relevant description of the indoor terrain environment.The advantages of BIM and GIS are complementary,and the combination of the two can achieve the integrated 3D expression of indoor and outdoor space and realize the combination of micro and macro.This paper designs and develops a BIM+GIS indoor and outdoor simulation prototype system.Based on the design framework,on the basis of OSGEarth SDK,through the secondary development of C++,the system inte-grates the above methods,realizes the 3D visualization scene of indoor and outdoor integrated space that integrates the four application modules of visual interaction,information interaction,interactive modeling and analysis and application,and realizes indoor and outdoor integrated task deduction for specific applications.
