Currently used 3D models, which are mostly focused on visualization of 3D objects and lack topological structure, have limitation in being used for 3D spatial analyses and applications. However, implementing a full topology for the indoor spatial objects is less practical due to the increase of complexity and computation time. In this study, an alternative method to build a 3D indoor model with less complexity using a spatial DBMS is suggested. It is a 2D-3D hybrid data model, which combines the 2D topology constructed from CAD floor plans and the 3D visualization functionality. We show the process to build the proposed model in a spatial DBMS and use spatial functions and queries to visualize in 2D and 3D. And, then, as an example application, we illustrated the process to build an indoor way-finding simulator.
