Design and Development of BIM on GIS Interoperability Open Platform

ecently, Construction data has evolved from CAD to BIM and BIM becomes more important data used in various fields like facility management and 3D GIS construction, so there is an increasing need for developing technologies that can be effectively used in post-construction steps. There are lots of trials to model and service not only geographical terrain and outdoor but also indoor space. From this perspective, establishment of BIM and GIS interoperable method and development of service platform became the most important core technology. On this research, spatial data linkage model has been devised to smoothly implement the interoperability between two different kinds of data - BIM data and GIS data.



The platform basically displays BIM data based on 3D GIS such as WorldWind Java developed by NASA and Google Earth. It is also possible to interactively move in and out the buildings and also to see the outside of the building when a user is inside the building and inside of the building while a user is outside the building. Besides, the platform makes users look up the objects of buildings and properties of objects one by one, floor by floor, by similar properties, or all. Users can also edit the properties of objects and do spatial queries for analysis of the data.



This project is co research project of KICT(Korea Institute of Construction Technology) and Gaia3D and working closely together to develop BIM and GIS Interoperability Open-Platform for the integration of BIM and GIS data since 2012 and have developed the system for smooth operation of big size 3D BIM data and GIS data about plenty of buildings in areas or cities, not just one building. Now, core technologies to integrate BIM into GIS are successfully developed and we will keep improving the system step by step. KICT and Gaia3D together have designed and developed BIM and GIS interoperability open-platform based on the spatial data linkage model. Links between BIM data and GIS data enables efficient and seamless management of indoor and outdoor information at the same time and it also could be used for various services such as real estates and AR (Augmented Reality) services. Gaia3D develops 3D facility management system for Antarctic King Sejong science station to efficiently manage the facilities and publicly promote the station using BIM on GIS system with open source GIS software.
