Sentinel Band Combinations True color in ArcGIS pro

Sentinel Band Combinations
We use band combinations to better understand the features in imagery. The way we do this is by rearranging the available channels in creative ways.

By using band combinations, we can extract specific information from an image. For example, there are band combinations that highlight geologic, agricultural, or vegetation features in an image.

RGB (4, 3, 2)
True color composite uses visible light bands red (B04), green (B03) and blue (B02) in the corresponding red, green and blue color channels, resulting in a natural colored result, that is a good representation of the Earth as humans would see it naturally.


False Color
RGB (8,4,3)
False color imagery is displayed in a combination of standard near infrared, red and green band. False color composite using near infrared, red and green bands is very popular. It is most commonly used to assess plant density and healht, as plants reflect near infrared and green light, while absorbing red. Since they reflect more near infrared than green, plantcovered land appears deep red. Denser plant growth is darker red. Cities and exposed ground are gray or tan, and water appears blue or black.

SWIR
RGB (12,8,4)
Short wave infrared (SWIR) bands 11 and 12 can help scientists estimate how much water is present in plants and soil, as water reflects SWIR wavelengths. Shortwaveinfrared bands are also useful for distinguishing between cloud types (water clouds versus ice clouds), snow and ice, all of which appear white in visible light. Newly burned land reflects strongly in SWIR bands, making them valuable for mapping fire damage. Each rock type reflects shortwave infrared light differently, making it possible to map out geology by comparing reflected SWIR light. In this composite, B8A is reflected by vegetation and shown in the green channel, while the reflected red band, highlighting bare soil and built up areas, is shown in the blue channel.
