Recently, various researches have been attempted to link or integrate BIM and GIS. In particular, some of the researches were progressed to convert the data model between the BIM standard model IFC and the GIS standard model CityGML. However, it is hard to utilize the previous research results yet because characteristics and domains of between two data models are very different, In order to obtain the correlation between BIM and GIS, in this research, we analyzed the characteristics between IFC and CityGML objects of each LOD, And, we analyzed the correlation of IFC and CityGML by performing mapping between IFC and CityGML objects from view point of building with these characteristics. In this research, based on these correlation analysis results, we proposed the efficient interrelation plan between IFC and CityGML.
