Abstract :
Within the scientific community there is a great interest in accurately mapping global vegetation and monitoring its change. Most of the vegetation mapping done at coarse resolutions (1-4 km) is done with a single sensor such as AVHRR. In contrast, this research ultimately seeks to improve the quality of low-resolution AVHRR global vegetation maps by including scatterometer and elevation data. In supervised discrimination experiments conducted using imagery of North Africa, SeaWinds combined with AVHRR Channels 2 and 4 produced the highest classification accuracy among several possible variable combinations
