Construction of Geographic Information Spatial Analysis System Based on BIM Technology

Spatial process is one of the basic movement forms of ecological environment, social economy and geographical system. Spatial analysis refers to a series of theories and techniques for analyzing, simulating, predicting and regulating spatial processes. With the support of BIM (building information modelling) technology, it can realize the real-time sharing of information, effectively reducing the shortcomings of traditional construction management process. Thus, the cooperation among different departments and specialties in the process of spatial analysis of geographic information is realized. The information integration of BIM technology mainly reflects the integration of the design process and the integration of design information. There is information when there are differences, and information is a reproduction of differences. Therefore, regional differences will inevitably lead to the generation of geospatial information flow. The powerful function of BIM technology can realize the simulation processing of geographic information analysis. BIM technology has changed the way of information transmission in the life cycle of construction projects, and effectively improved the connection efficiency between design and management. This paper studies the construction method of geographic information spatial analysis system based on BIM technology.
