Vulnerability Heatmapping in Debris Management

Abstract

Debris generated and left in the wake of a disaster is one of a community’s greatest obstacles in the ability to restore function. The objectives of this paper are (1) to provide systematic procedures to develop and visualize the vulnerability index (VI) based on three dimensions, and (2) to prioritize debris removal by integrating all dimensions into a geographic information system (GIS). The proposed methodology for vulnerability heatmapping consists of three dimensions: (1) physical, (2) infrastructure, and (3) environmental. An unmanned aerial vehicle (UAV) is used to quantify the debris three-dimensional (3D) volumetric information as part of the 11 metrics selected and evaluated to establish the vulnerability of a location. The proposed process incorporates all systems into a process to allow decision makers to quickly determine scope, complexity, potential impact, and recovery needs. Therefore, the outcome of this research will ensure maximum and timely utilization of limited resources to reach a greater number of people who might be facing life-threatening situations, enhancing the community’s resilience.
