- •
Spatial and spectral requirements for early laurel wilt detection were evaluated.
- •
The effective wavelengths to separate laurel wilt were identified.
- •
The ideal flight altitude was 250 m (15.3 cm pixel size).
- •
The optimum VIs were TCARI760–650, GNDVI, NIR/G, Redge/G and VIGreen.
- •
It should be more convenient to develop the algorithm based on a 4 class system.
