The shape of the reflectance spectrum can be used for identification of vegetation type. For
example, the reflectance spectra of dry grass and green grass in the previous figures can be
distinguished although they exhibit the generally characteristics of high NIR but low visible
reflectance. Dry grass has higher reflectance in the visible region but lower reflectance in the
NIR region. For the same vegetation type, the reflectance spectrum also depends on other factors
such as the leaf moisture content and health of the plants. These properties enable vegetation
condition to be monitored using remotely sensed images.
