Prototype Development of a Spatial Information Management System for Large-Scale Buildings

This paper presents a new model of a management system for large-scale buildings that aims to deal with both static and dynamic spatial information. For this purpose, 3D CAD, 3D GIS and image processing are integrated. The geometrical information of a building is managed by GIS using a database built from 3D CAD. Also, the dynamic spatial information of a building (i.e., flow size of pedestrians) is obtained using image processing. We implemented a prototype version of the proposed system to a real environment and it showed promising results for a running system covering a wide area.
