Using the spectra reflectance plot tool

In the Spectra Reflectance Plot window, you can work with layers that are reflectance data. The plot and the tools are linked to the image selected on the Maps tab.

You can compare the image reflectance values with the library signatures of known features. By doing so, you can validate the results from the atmospheric-correction process.

By plotting reflectance spectra with the interactive graph tool, you can validate the results of your atmospheric correction by comparing the values with those in a spectral library.
