The concept of a "spectral signature", another name for a plot of the variations of reflected (or absorbed) EM radiation as function of wavelengths, gives rise to the widely used approach to identifying and separating different materials or objects using multispectral data obtained by remote sensors.

A spectral signature is a unique reflectance value in a specific part of the spectrum. Displayed in the graph below are the spectral signatures for healthy green vegetation, stressed vegetation, and severely stressed vegetation.

The downward illumination may be described briefly by two signature types: the downwards spectral irradiance and the diffuse proportion of the downwards spectral irradiance.

Once the spectral signature is calibrated to identify known stands, then the spectral signature could be used to identify other stands (not ground verified with GPS) of the same species, therefore predicting their location.

The impact of wind on the spectral signature of crop ... On August 4, 1998 NASA's Advanced Thermal and Land Applications Sensor (ATLAS) was flown over experimental fields in southwestern Georgia. The flights were designed to acquire high resolution (~2.5 meter) imagery over the farm at least twice within 30 minutes.

The present study explores the potential advantages of using the far-infrared spectral signature for investigating the microphysical and radiative properties of ice clouds (cirrus clouds, in particular). These clouds have a significant impact on the terrestrial climate system through their radiative effect.
