Multispectral imaging works by using sensors that can detect light at different wavelengths. In agriculture, for example, multispectral imaging can be used to measure plant health by detecting the reflection of light off leaves. Healthy plants absorb more light in the visible spectrum and reflect more in the near-infrared spectrum, making it possible to detect differences in plant health based on the amount of light reflected at different wavelengths.

In addition to agriculture, multispectral imaging has a range of other applications, including environmental monitoring, infrastructure inspections, and surveying. For example, multispectral imaging can be used to detect oil spills or monitor water quality in bodies of water. It can also be used to inspect infrastructure, such as bridges or wind turbines, for damage or wear and tear.

Overall, drones can use multispectral imaging to provide detailed and precise data that would be difficult or impossible to obtain through traditional methods. With its broad range of applications, multispectral imaging is becoming an increasingly valuable tool for a variety of industries and purposes.
