Spectral-band correlation, radiometric conversion, and sample collection by clipping the images of the crowns of A. angustifolia and H. dulcis. A Correlation between the 8 spectral bands of the WorldView-2 sensor; composition choice: near-infrared (NIR-2=950 nm, G=545 nm, B=480 nm) and true color composition (R=660 nm, G=545 nm, B=480 nm); and radiometric conversion. B Collection of samples by clipping the crowns of A. angustifolia and H. dulcis in 20 × 20px, in both compositions, in simultaneous confirmation with the RPA’s images
