Fig. 4c. Reflectance of different plants. The olive tree (Tuscany) and the wheat
(Matera) reach the highest values while the matorral (Castilla-La Mancha) and
macchie vegetation remains at lower levels in the near infrared. The matorral vegetation
is sparse. The underlying soil enhances the reflectance at 650 nm

Fig. 4d. At 800 nm normalized spectral reflectance of some plants showing a very
similar normalized spectral behaviour. The coloured lines show the spectra of cherry
leaves, pistachio lentiscus (Mas), olive, and rosemary.
