Rapid Disaster Mapping through Data Integration from UAVs and Multi-sensors Mounted on Investigation Platforms of NDMI, Korea

Abstract

<p><strong>Abstract.</strong> As the recent disaster is so difficult to predict when and where it would hit, so it requires paradigm for disaster shifts from response to preparedness. In order to respond this change, NDMI has studied disaster scientific investigation (DSI) technologies for revealing systematically the root cause of disaster and protecting repetitive recurrence.<br> The purpose of this study is to propose a convergence approach between data acquired from different types of sensors on a van-type investigation platform and UAVs of NDMI and assess their applicability for timely natural and man-made disaster mapping and monitoring. In order to evaluate its applicability for rapid disaster mapping, we pre-tested the proposed approach for NDMI site in Ulsan, Korea. For the enhancement of the direct geo-referencing accuracy of UAV imagery captured from on-board camera of DJI and the creation of more accurate map products, camera IOPs refinement and bundle adjustment were also performed with minimal GCPs. Finally, we conducted UAV data registration with LiDAR point clould for disaster mapping applications.</p>

Disaster Damage Investigation Using Artificial Intelligence and Drone Mapping

“…In order to identify the root cause of a disaster occurrence and investigate damage (Figure 1), the NDMI (National Disaster Management Research Institute) uses cutting-edge technologies and equipment such as drones and special vehicles to monitor the disaster accident site, analyse collected information using AI, spread the situation, and support decision-making (Kim et al, 2018(Kim et al, /2019.…”

“…As the feasible operational tools for DSI, NDMI has started to adopt and operate the various types of investigation platforms and devices: a MMS-type specialized vehicle, Unmanned Aerial Vehicles (UAVs), ultrasonography detector, rebar detector, etc. (Kim et al, 2018). Since flood events by Hurricane Katrina in 2005, a variety of drone have been used in the wide applications for disaster management.…”

Risk Assessment of Steep Slope Using Drone Mapping and Terrestrial Lidar in Korea

“…As the feasible operational tools for DSI, NDMI developed a disaster investigation platform that converted a van in 2015 to investigate effectively and systematically the damage and the cause of a variety of disaster accident. This investigation vehicle is equipped with various disaster accident field investigation sensors such as MMS (Mobile Mapping System) with terrestrial LiDAR that can acquire 3D point cloud data during normal running speed, high resolution optical and thermal imaging cameras, and weather observation equipment as shown Table 1 (Kim et al, 2018).…”
