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. Unlike previous systems for building management, the proposed system aims to deal with both static and dynamic spatial information in a single framework. For this purpose, 3D CAD, 3D GIS and image processing are integrated together. In the proposed system, the geometrical information of a building is managed by GIS using a database built from 3D CAD. Also, the dynamic spatial information (i.e., flow size of pedestrians) is obtained using imageprocessing. 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.
