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

Natural Color<\/span>: 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.<\/span><\/p>

Color Infrared: <\/span>The Color Infrared composite is created using the near-infrared, red, and green channels, allowing for the ability to see areas impacted from the fires. The near-infrared gives the ability to see through thin clouds. Healthy vegetation is shown as red, water is in blue.<\/span><\/p>

True Color: <\/span>The True Color RGB composite provides a product of how the surface would look to the naked eye from space. The RGB is created using the red, green, and blue channels of the respective instrument.<\/span><\/p>

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

Natural Color: <\/span>areas of water will appear blue, healthy green vegetation will appear as a bright green, urban areas in various shades of magenta.<\/span><\/p>

Color Infrared: <\/span>depicts healthy vegetation as red, water as blue. Some minor atmospheric corrections have occurred.<\/span><\/p>

True Color: <\/span>provides a product of how the surface would look to the naked eye from space. The True Color RGB is produced using the 3 visible wavelength bands (red, green, and blue) from the respective sensor. Some minor atmospheric corrections have occurred.<\/span><\/p>
