Which remote sensing band is most sensitive to soil moisture variations?
A. Near infrared (NIR)
B. Shortwave infrared (SWIR)
C. Thermal infrared (TIR)
D. Blue band
Answer: Option B
Solution (By Examveda Team)
SWIR is sensitive to moisture content due to absorption properties.This makes it useful for mapping soil moisture and drought monitoring.This Question Belongs to Geological Engineering >> Remote Sensing And GIS In Geological Engineering
