BSI (Bare Soil Index)
Identifies exposed soil areas using shortwave infrared and visible bands.
The Bare Soil Index uses a combination of SWIR, Red, NIR, and Blue bands: BSI = ((SWIR + Red) - (NIR + Blue)) / ((SWIR + Red) + (NIR + Blue)). Higher values indicate more exposed soil.
BSI is useful for mapping tillage patterns, detecting erosion-prone areas, and monitoring soil cover between crop rows. In precision farming, it helps identify areas where soil conservation practices may be needed.
