다국어 초록 (Multilingual Abstract)

High-rise and large-scale buildings are increasingly dominant to efficiently and economically utilize limited space in metropolitan cities. Particularly, in complex buildings connected to underground facilities, a significant number of people uses indoor spaces for various purposes, leading to increasing demands for network-based spatial information services such as path finding and facility management. Indoor networks exhibit various structures and accuracy depending on the raw data and surveying techniques used during construction. Different networks within spatial information systems can cause spatial consistency and inter-operability problems. In this regard, the paper proposes an indoor linear reference system(LRS) to systematically manage and efficiently associate spatial information. The LRS defines a linear datum and linear reference method to locate spatial information along linear paths. With this system, indoor networks with different coordinate systems and scales can consistently record and inter-operate spatial information. In this research, the LRS was empirically constructed in a indoor test bed to confirm its adaptability and efficiency.
