Drones can be quickly deployed, generating high-resolution and 3D mapping, identifying hotspot areas with the most damage, and uploading the data in real-time to help coordinate relief efforts.
FREMONT, CA: Drones have received mixed reviews because of their associations with an invasion of privacy and armed deployment in war. Another, more positive application provides safety, protection, and disaster relief. Natural and man-made disasters wreak havoc on the environment, making it difficult for relief workers to reach affected areas and provide assistance. Drones can fill in for relief workers and manned vehicles when they are unavailable.

Hazardous Chemical Spills
For a variety of reasons, hazardous or nuclear chemicals can leak into the environment. Factory or power plant failures spills during transportation, and even terrorist attacks are some of the causes. In these and similar situations, determining the extent of the damage and providing relief must be done quickly and efficiently. CBRNE (chemical, nuclear, biological, radiological, or explosive) events put people in danger, not only for those exposed to hazardous materials in the area but also for relief workers.
A powerful earthquake struck Japan in March 2011, causing a tsunami that wreaked havoc on one nuclear power plant. Because of the quantity of dangerous nuclear material released, the damage necessitated a full-scale evacuation. Drones were launched into the air and onto the ground as soon as possible to evaluate the extent of the damage. These unmanned vehicles were able to monitor radiation exposure, fix destroyed areas, and rebuild efforts, all while keeping relief workers safe from nuclear fallout.
The Importance of Mapping
Visual imaging and 3D mapping are instrumental in areas prone to large-scale disasters like earthquakes and flooding. Human-crewed aircraft are often prohibitively expensive, satellite mapping falls short of high-resolution requirements, and both take too long in emergencies.Compared to traditional methods, using drones to map disaster areas offers more cost savings and faster response times. Drones can be quickly deployed, generating high-resolution and 3D mapping, identifying hotspot areas with the most damage, and uploading the data in real-time to help coordinate relief efforts.
Drones assisted in creating 3D maps and models in the aftermath of the 2015 Nepal earthquake using image processing software. These help in assessing the extensive damage, conducting search and rescue missions, rebuilding buildings, and preserving city areas.
