Spectral Characteristics Viewer
The Spectral Characteristics Viewer allows users to determine which satellite bands are best suited for their research application.
How to use the Spectral Characteristics Viewer
- Click on the “Bands/Spectra/Convolve” button and select the bands from the available satellite instrument(s) to view how they measure the intensity of the wavelengths (colors) of light (also known as Relative Spectral Response -RSR).
- From the “Spectra” tab select from minerals, vegetation, water or coating-rocks to plot their spectral response alongside the bands from the satellite instrument(s).
- Click “Close” to view the spectral characteristics results.
To capture spectral characteristics results please use system and web browser print functions.

Spectra: The USGS Spectroscopy Lab contains the spectra source information available in this viewer.
Convolve: While the full process of convolve is to simulate how a satellite sensor detects a surface feature in each spectral band, in this current viewer version, the Convolve function displays only the full width at half maximum values (FWHM) for the selected satellite bands; full convolve functionality will be included in a future update of this viewer.
