This paper examines the use of unmanned aircraft systems (UAS) to capture imagery for use in post-disaster field studies at the neighborhood and individual building level. Applications of UASs in recent disasters as described in the literature are reviewed, and a case study investigating UAS capabilities for imagery collection following an EF-3 tornado in northern Alabama on March 2, 2012 is presented. Case study considerations include the multi-rotor UAV equipment and ground station, onboard imagery devices, flight considerations and capabilities, and imagery and metadata collection capabilities of the UAS. Sample post-tornado imagery of building damage is shown, demonstrating the order of magnitude improvement in imagery resolution compared to traditional post-disaster aerial photography.
