Abstract
This study introduces the BIM (building information modeling)-GIS (geographic information system) conceptual mapping (B2GM) standard ISO N19166 and proposes a mapping mechanism. In addition, the major issues concerning BIM-GIS integration, and the considerations that it requires, are discussed. The B2GM is currently being standardized by the spatial-information international standardization organization TC211. Previous studies on BIM-GIS integration seem to focus on the integration of different types of model schemas and on the implementation of service interfaces. B2GM concerns the clear definition of the conditions and methods for mapping the object information required from the user’s use-case viewpoint for city-scale mapping. The benefits of the B2GM approach are that the user is able directly control the BIM-GIS linkage and integration process in order to acquire the necessary objection information. This can reveal cases of possibly unclear BIM-GIS integration outside the black box in an explicit and standard way, so that the user can distinctively predict the final output obtainable from the BIM-GIS integration. This study examined B2GM in terms of its development background, components, and several utilization examples, as well as the levels and considerations of the integration of different BIM-GIS models.
Highlights
The integration of data through geographic information system (GIS)-based building information modeling (BIM) has emerged as an important area of research for the mining of valuable information that can support decision-making.In particular, in order to realize smart city services such as facilities including effective building and energy management, we need to consider the information perspective, which can be represented by considering use cases related to services and combining the BIM and GIS information that we want to use, including information on the building and infrastructure objects in a city
Diverse approaches are used for the research on GIS-BIM integration, but this chapter summarizes the research contents from the perspectives of ontological modeling, integrated web services, schema mapping, and schema expansion and development
Interoperability implementation based on ontological models enables data integration at the conceptual level
Summary
The integration of data through geographic information system (GIS)-based building information modeling (BIM) has emerged as an important area of research for the mining of valuable information that can support decision-making. We need to consider other heterogeneous data models, such as facility management (FM) database systems. Outdoor–indoor linking services, such as seamless navigation; and Effective facility/energy/environment management considering objects related to BIM based on GIS.
