        This tutorial has been written to demonstrate how color images are
        generated from the data sent from Landsat satellites.

        Landsat satellites collect electronic images with seven specially
        designed optical sensors.   Each sensor is designed to collect
        light of a specific color or color region.  The satellite then
        sends these images to the ground station where they are processed
        into black and white pictures.  The different bands are usually
        combined by the users to generate "false" color pictures.

        These color pictures usually show up details which cannot be
        seen by the naked eye.

        With this program, you will be able to view each individual band
        and generate your own "color" images of the Grand Canyon.
