Over the past few years airborne remote sensor devices have been developed for different regions of the electromagnetic spectrum that are capable of collecting data on the reflective and emissive properties of terrain. However, experience has shown that the capability to collect data of this type is not, in itself, sufficient to permit its fullest use. In almost every case, data collected with an airborne electromagnetic sensing system remote sensor must be augmented by data that define conditions existing in the environment at the time the remote sensor was used. The environmental factors that influence the electromagnetic energy received by remote sensing devices are defined for the following spectral regions a gamma ray, b ultraviolet, c visible, d infrared, and e microwave. In addition, the remote sensing devices used in each spectral region are discussed and the environmental factors appraised for relative importance with respect to the final remote sensing product.
