Summary:<\/span><\/p>

  • The Natural Color RGB provides a false composite look at the surface. This RGB uses a shortwave, the near-infrared, and red channels from the instrument. This image composite is at 30 m resolution.<\/span><\/p><\/li><\/ul>

    • The True Color RGB used the red, green & blue channels on Landsat 8 to provide a true color image of the earth surface, and should be most familiar to all users. This image composite is at 30 m resolution.<\/span><\/p><\/li><\/ul>

      • The Modified Normalized Difference Water Index (MNDWI) provides a different view of the Earth's surface combining different bands to make water bodies more obvious. This index can be used to identify flooded areas as well as heavily saturated areas.<\/span><\/p><\/li><\/ul>

        Suggested Use:<\/span><\/p>

        • Natural Color RGB: Areas of water will appear blue, healthy green vegetation will appear as a bright green, urban areas in various shades of magenta, clouds appear as white or bright blue, and bare soils being multicolor dependent on their makeup.<\/span><\/p><\/li><\/ul>

          • True Color RGB: The True Color RGB provides a product of how the surface would look to the naked eye from space.<\/span><\/p>

            <\/p><\/li>

          • MNDWI: Areas of existing water, such as a rivers or lakes appear in the darkest green with high values near 1, while dry land appears in the darkest brown with low values near -1. This product can be used to identify potentially flooded areas that can be seen in varying shades of green and light brown depending on the amount of moisture picked up by the satellite.<\/span><\/p><\/li><\/ul>
