This paper’s purpose is to establish a methodological basis for using unmanned aerial vehicles (UAV) in urban search and rescue (USAR). Modern USAR operations involve the location, rescue (extrication), and initial medical stabilization of individuals trapped in confined spaces or places with complicated access, eg, high structures. As a part of the ongoing modernization process, this paper explores possible options for UAV utilization in USAR operations. Today, UAV are already taking part in support emergency operations all over the world, and possible forms of operation for UAV in USAR environment can be in two primary modes: on-site and logistic chain. The on-site mode includes various capabilities of multilayer UAV array, mostly based on enhanced visual capabilities to create situational awareness and to speed-up search and rescue (SAR) process including using nanodrones for entering into confined places, ventilation ducts, and underground sewer channels can give to rescue teams’ opportunities to have eyes within ruins even before initial clearing process. Cargo drones will be able to bring equipment directly to high floors or roadless areas in comparison to wheeled transportation. The advantages of cargo drones operation are the ability of autonomous flight based on GPS or homing beacon and ability to provide logistics supports without involving additional personnel and vehicles and with no dependence on road conditions.

The need for accurate and spatially detailed hydrologic information is critical due to the microscale influences on the severity and distribution of flooding, and new and/or updated approaches in observations of river systems are required that are in line with the current push towards microscale numerical simulations. In response, the aim of this project is to define and illustrate the hydrologic response of river flooding relative to microscale surface properties by using an unmanned aerial system (UAS) with dedicated imaging, sensor, and communication packages for data collection. As part of a larger project focused on increasing situational awareness during flood events, a fixed-wing UAS was used to overfly areas near Greenwood, MS before and during a flood event in February 2019 to provide high-resolution visible and infrared imagery for analysis of hydrologic features. The imagery obtained from these missions provide direct examples of fine-scale surface features that can alter water level and discharge, such as built structures (i.e., levees and bridges), natural storage features (low-lying agricultural fields), and areas of natural resistance (inundated forests). This type of information is critical in defining where and how to incorporate high-resolution information into hydrologic models and also provides an invaluable dataset for eventual verification of hydrologic simulations through inundation mapping.

Manned-Unmanned Teaming (MUM-T) is a military concept that employs unmanned aerial systems (UASs) in support of traditional manned aircraft. The current ratio of manned to unmanned aircraft in MUM-T operations is one to one with a goal to expand to multiple UASs to further enhance the capability, but this imposes significant challenges on the operator. To address these challenges, this research implemented automated UAS behaviors combined with a pilot-vehicle interface tailored to provide supervisory control over multiple UASs. Results demonstrated that this combination of technologies allows a single crewmember to effectively manage up to three UASs while executing complex MUM-T tactical missions with manageable workload, improved situational awareness, and improved mission performance. Experimental results also identified areas where the current implementations can be further refined.

Image-guided military operations embed soldiers into a complex system of image production, transmission, and perception. These soldiers separate their bodies from the battlefield, but they also mediate between them. In particular, remote controlled operations of so-called unmanned aerial systems (UAS) require the synchronization between human actors and technical sensors in real-time, such as the knowledge of a situation. This situational awareness relies almost exclusively on the visualization of sensory data. This human-machine entanglement corresponds to a new operative modality of images which differs from previous forms of real-time imaging such as live broadcasting, as it is based on a feedback-loop that turns the observer into an actor. Images are not simply analyzed and interpreted but become agents in a socio- technological assemblage. The paper will draw upon this functional shift of images from a medium of visualization towards a medium that guides operative processes. Based on the analysis of vision, architecture, and navigation in remote warfare, it will discuss how real-time video technology and the mobilization of sensor and transmission technology produce a type of intervention, in which action and perception is increasingly organized and determined by machines.

Unmanned aerial systems (UAS) has many advantages in the fields of SURVAILLANCE and disaster management compared to space-borne observation, manned missions and in situ methods. The reasons include cost effectiveness, operational safety, and mission efficiency. This has in turn underlined the importance of UAS technology and highlighted a growing need in a more robust and efficient unmanned aerial vehicles to serve specific needs in SURVAILLANCE and disaster management. This paper first gives an overview on the framework for SURVAILLANCE particularly in applications of border control and disaster management and lists several phases of SURVAILLANCE and service descriptions. Based on this overview and SURVAILLANCE phases descriptions, we show the areas and services in which UAS can have significant advantage over traditional methods.

Less than two weeks after Hurricane Florence made landfall in North Carolina (NC), a team of researchers from NC State University traveled to Dare County to investigate the storm’s effects on beaches and dunes. Using available post-storm imagery and prior knowledge of vulnerabilities in the system, the team identified several locations to visit in the towns of Kitty Hawk, Nags Head, Rodanthe, Buxton, and Hatteras, as well as a number of locations within the Pea Island National Wildlife Refuge (Figure 1). Data collected included topographic profiles, still imagery and video from unmanned aerial systems, sediment samples, and geo-located photography. This Coastal Observations piece presents some of the data and photos collected; the full report is available online (Sciaudone et al. 2019), and data collected will be made available to interested researchers upon request.
