"What are the best spectral bands to use for my study?"
This is a common question from all users of remotely sensed data. The spatial resolution (level of detail) is often the most interesting aspect of a satellite image, but less appreciated is how changes in irradiative energy reflected by surface materials are used to identify features of interest.
The Spectral Characteristics Viewer allows us to visualize how the bands of various satellite sensors measure the intensity of the wavelengths (colors) of light; this is called the Relative Spectral Response (RSR).
By overlaying the spectral curves from different spectra (features), the user can determine which bands of the selected sensor(s) will work for the application.

Landsat represents the world's longest continuously acquired collection of space-based moderate-resolution land remote sensing data. Four decades of imagery provides a unique resource for those who work in agriculture, geology, forestry, regional planning, education, mapping, and global change research. Landsat images are also invaluable for emergency response and disaster relief.
