Digunakan untuk apa?

Konversi TOA Radiance ke  TOA Reflectance (ρ)

ρ=(π*Lλ *d^2)/(Esunλ *cosθ)

dimana:
ρ = Unitless Planetary Reflectance
Lλ = Spectral Radiance at The Sensor’s Aperture
d2 = Earth-Sun Distance in Astronomical Units
ESUNλ = Mean Solar Exoatmospheric Irradiances
θ = Solar Zenith Angle in Degrees
