WebIt uses the blue reflectance region to correct for soil background signals and to reduce atmospheric influences, including aerosol scattering. EVI values should range from 0 to 1 for vegetation pixels. Bright features such as clouds and white buildings, along with dark features such as water, can result in anomalous pixel values in an EVI image. WebJun 23, 2015 · It was determined that reflectance near the 710-nm wavelength showed maximum sensitivity to chlorophyll content. The ratio of the first derivative of 754 and 704 nm and the red edge are best correlated to chlorophyll content, and the second derivative of 712 and 688 nm is also an equally good indicator of chlorophyll content (Datt 1999 ).
