• Savannas: We separate the savannas into two classes:
“Grass Savanna” (Sav) and “Woody Savanna” (Woo).
The latter is not identified on the available land cover
map. However, the existence of this class is documented
by ground surveys. The Woody Savanna has seasonal
characteristics and can also host extensive fire events.
These facts are reflected in relative changes between the
backscatter values of the two acquisition dates.
