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

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>

The Short Wave Infrared (SWIR) RGB is a product that is created using the SWIR, NIR, and Red channels of the respective instrument.<\/span><\/p>

The Color Infrared composite is created using the near-infrared, red, and green channels, allowing for the ability to see areas impacted by 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>

The Normalized Burn Ratio identifies burned areas using <\/span>this calculation<\/span><\/a>. Darker areas are potentially burned areas.<\/span><\/p>

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

The True Color RGB 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>

The Short Wave Infrared (SWIR) RGB is a product that can provides value in flood detection. Areas of water will appear blue, healthy green vegetation will appear as a bright green, urban areas in various shades of magenta, snow will appear as a bright blue/cyan, and bare soils being multicolor dependent on their makeup. Compare pre-event imagery to post-event imagery to identify potential affected areas.<\/span><\/p>

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