A USGS tool to figure out which satellite band to use for Remote Sensing


The United States Geological Survey (USGS) has developed a very useful and unique tool named as the Spectral Characteristics Viewer . The Spectral Characteristics Viewer allows users to determine which satellite bands are best suited for their research application.

After selecting the band numbers of the available satellite instrument(s) one can view how they measure the intensity of the wavelengths (colors) of light (also known as Relative Spectral Response -RSR).


It also has the facility to select the spectra of some minerals, vegetations, water types and coating rocks. So we can come to how spectrum of a feature looks like for a particular satellite imagery data.
