Abstract
An essential prerequisite for reducing natural disaster damage is to identify objects vulnerable to extreme weather events. However, it is not trivial to scrutinize large urban areas within a short period of time, using conventional data collection processes for disaster preparedness. To address this issue, we propose a novel geospatial localization method building on participatory sensing to localize vulnerable objects or areas in cities. The proposed method consists of sequential modules-a geographic coordinate conversion, mean-shift clustering, deep learning-based object detection, magnetic declination adjustment, line of sight equation formulation, and the Moore-Penrose generalized inverse method-to localize urban objects in crowdsourced data. The localization accuracy of the proposed method is evaluated in a case study of urban areas in Texas. The proposed method is expected to contribute to rapid data collection practice in disaster preparedness and enable practitioners to concentrate their limited resources on where focus is needed.
