The integration and application of BIM and GIS in modeling

Abstract

Refinement, intelligence, and standardization are the core requirements of today's urban construction management. From the current situation, it is impossible to meet the needs of future urban construction and management by relying on a single technology. The integration of GIS and BIM provides new opportunities for urban construction management. GIS provides a basic framework for the construction and management of today's cities, and BIM provides an accurate information model of a single building for urban construction management. The integration of GIS and BIM will bring new ideas and methods to city construction and management. A large number of high-precision BIM models provide detailed building information for city management and provide richer information for the construction of city 3D models. Although the fusion research of GIGIS and BIM has clear directions and urgent needs, the fusion research work of the two is still in the initial and exploratory stage.
