It is able to capture flooded areas.

DRONE images use infrared, a type of photo that blocks most of the visible light spectrum. Nearby infrared images can be processed to create a Normalized Difference Vegetation Index (NDVI), which is a calculation of the cropping field that covers the field. A stress agent that slows plant growth or begins to degrade plants can be identified by NDVI before it is visually apparent.
