NASA | Peeling Back Landsat's Layers of Data

The video tutorial explains how satellites collect data across different wavelengths, including infrared and visible light, to create images of Earth's surface. It describes natural color images, which resemble what we see with the naked eye, and false color images, which use different wavelength combinations to highlight specific land features. The tutorial also covers the use of color infrared film to depict healthy vegetation and compares various multispectral data depictions to show how surface features can be enhanced.
