A variety of data can be collected by unmanned aircraft and sensor combinations. One example is spectroscopy, which captures the entire spectrum of light. It gives analysts the ability to discriminate specific chemicals and elements and monitor subtle changes in the visible and near-infrared radiation that plants reflect.
Using cameras that can measure reflective properties of materials allows a spectroscopy data set to be created that can aid in telling different materials apart. Measuring more than one band at a time can help create a graph of the reflective properties at each of these bands. Graphing the reflective properties of each of the bands measured gives the client a graph that can be used to tell differences between materials that otherwise might look the same but contains different elements.
In addition to agriculture, unmanned aircraft technology can be used to service fields in biology, forestry, mining, environmental research, and infrastructure inspection.
