Description

Data Integration System and Method for BIM and GIS Integrated Spatial Information Platform This study is the result of research conducted as part of the Digital Land Information Technology Development Project (2610000052) supported by the Ministry of Land, Infrastructure and Transport and the Korea Institute of Land, Infrastructure and Transport Technology. The present invention relates to a data integration system and method for a BIM and GIS integrated spatial information platform, and more specifically, to a data integration system and method for a BIM and GIS integrated spatial information platform that integrates Building Information Modeling (BIM) and Geographic Information System (GIS) data to effectively visualize and utilize BIM data on a GIS spatial information platform. As the need for smart city management increases, the integration of BIM and GIS is emerging as an important topic. BIM is a digital representation of the physical and functional characteristics of a building and is widely used in the construction industry for detailed design, construction, and facility management. However, due to the complex data structure of BIM, it is difficult to perform spatial analysis using this data in a GIS environment. On the other hand, while GIS provides tools for geographic visualization and spatial analysis, it has the problem of lacking detailed semantic information about building components provided by BIM. In addition, while existing studies have explored methods to integrate BIM data with GIS platforms, difficulties such as data loss and performance issues during visualization still exist. Existing approaches often convert BIM data into simplified formats, which can lead to the loss of important information.

The present invention relates to a data integration system and method that integrates Building Information Modeling (BIM) and Geographic Information Systems (GIS) to efficiently visualize and utilize building and city information on a spatial information platform. Building Information Modeling (BIM) is a method of digitally representing the physical and functional characteristics of a building; it is utilized at all stages of a building's lifecycle, such as construction, design, and maintenance, and provides detailed information about building elements. Geographic Information Systems (GIS) are systems for the visualization of geographical information and spatial analysis; they are specialized in processing and managing spatial data and play an important role in urban planning and infrastructure management. The integration of BIM and GIS enables better management and analysis based on the complementarity of the information handled by each system. While BIM handles detailed internal information of a building, it has limitations in understanding the interrelationships with the surrounding environment in which the building is located. Conversely, GIS includes external spatial information of a building but has limitations in providing internal configurations and detailed information about individual buildings. Therefore, integrating BIM and GIS enables comprehensive visual
