A Development Direction of a New Archi Urban Integration Model for Utilizing Spatial Information
For efficient interoperability of information between IFC (a standard open BIM model) and CityGML(a standard model in GIS) the information system is comparatively analysed through IFC, CityGML and LandXML. A direction for developing object oriented AUIM (Archi Urban Integration Model) for analysis and maintenance of spatial information is proposed. In this study, LOD for AUIM based interior spatial information is presented. At the same time, strategies for BIM GIS convergence are sought.
