A Grid-Based Identification Code for Buildings: Perspective from Spatial Fault Tolerance

Abstract

Buildings are important elements in modern cities, and the identification of buildings provides the foundation to smart city construction. In this paper, we aimed to put forward a new identification code for buildings from the aspect of spatial fault tolerance. Taking the location information into consideration, buildings were identified with one-dimensional integer codes based on discrete global grid system (DGGS). Results illustrated that this identification code could express location information of buildings explicitly, and remained unchanged even when there were tiny spatial offsets. The percentage of unchanged codes was 90%, 81%, 65% 32% under different offsets of 0.5 m, 1 m, 2 m and 5 m, respectively. We concluded that this identification code was conducive to the more efficient management of buildings, and might additionally benefit the smart city construction.
