“What are the best spectral bands to use for my study?”
This is a common question considered by all users of remotely sensed data. The level of detail (spatial resolution) is often the most interesting aspect of viewing a satellite image, but less appreciated is how changes in irradiative energy reflected by different surface materials are used to identify features of interest.
This interactive tool developed by scientists at the USGS Earth Resources Observation and Science (EROS) assists to visualize how the bands, or channels, of different satellite sensors measure the intensity of the many wavelengths (colors) of light; this is called the relative spectral response (RSR). By overlaying the spectral curves from different features (spectra), the user can determine which bands of the selected sensor will work for your application.
