Visual interpretation of vegetation, classification.
Urban areas appear blue-grey. 4 3 2.
The band combination chosen makes vegetation appear in shades of red because vegetation reflects a lot of near infrared light. False color imagery is displayed in a combination of standard near infra-red, red and green band. Shortwave infrared (red), near infrared (green), and green (blue), often used to show floods or newly burned land. A false-colour composite image with georeferencing is created. A false color image is made with one or more bands from a non-visible portion of the electromagnetic spectrum that are mapped to red, green, and blue colors. The brighter the red, the healthier the vegetation. This is a traditional band combination useful in seeing changes in plant health.
In this false color composite vegetation appear bright green, bare ground appears reddish and snow appears bright blue.
Agriculture. False Color (urban) 7 6 4. This band combination makes use of the NIR, SWIR2, and Coastal Aerosol bands, respectively. Color Infrared (vegetation) 5 4 3. Here’s a rundown of some common band combinations applied to Landsat 8, displayed as a red, green, blue (RGB): Natural Color. Custom script: return [B08, B04, B03]; Our four most common false-color band combinations are: Near infrared (red), green (blue), red (green). The Coastal Aerosol band is unique to Landsat 8 and is used primarily to track fine particles like dust and smoke, and also to peer into shallow water.
Another common combination uses the shortwave infrared (shown as red), the near infrared (green), and the green visible band (shown as blue).
We can also choose band combinations from other wavelenghts, and map them to the red, blue, and green colors to highlight different features. 5, 7, 1 - False color for vegetation and water, Lake Victoria, Tanzania.
