A drone survey for disaster response refers to the use of a drone to capture aerial data with downward-facing sensors, such as RGB or thermal payloads. During a drone survey with an RGB camera, the ground is photographed multiple times and each image is tagged with coordinates.
After flight, these photos are processed in photogrammetry software such as PIX4D or Agisoft Metashape. The photogrammetry software can then recreate geo-referenced 3D maps, contour lines, digital terrain models, or digital surface models to be reviewed in geospatial software such as ArcGIS or QGIS.
When environmental disasters strike, the first 72 hours are critical. The more information responders know about the changing environment the better. Live aerial view from gimbaled EO/IR (visible and thermal video) cameras can reveal current conditions on the ground, giving responders the information they need to respond.
A drone can safely fly at very low altitudes and in dangerous areas providing the aerial perspective first responders need without risking manned aircraft or taking them from other duties only they can perform. A drone is an affordable solution to provide to smaller units and doesn’t require extensive upkeep or ongoing training like other forms of aviation.
With the ever increasing damage from wildfires, the U.S. Department of the Interior and other agencies have turned to drones to help extinguish wildfires, quantify the damage, and plan for rehabilitation.
A drone equipped with an EO/IR (Electro-Optical/Infra-Red) camera has the ability to send live thermal data along with coordinates to the main command station for the fire chief to assess. By monitoring the edge of the fire as well as the hot spots inside the fire, a fire chief has the ability to better direct ground crew as well as air attack units attempting to halt the spread of the fire.
The vast damage that a wildfire creates is extremly hard to quantify with anything except aerial imagery. Smoke can sometimes linger for up to two to three weeks making photography from manned aircraft unviable. Drones have the ability to fly at lower altitudes, avoiding much of the smoke, allowing expedited creation of maps in order to plan a recovery roadmap or perform root cause analysis.
