Abstract :
The authors have compared NDVI and the feature mixing model as a practical semi-quantitative measure of daily vegetation. In the comparison, they used AVHRR data for a warm, humid and relatively flat eastern China. While NDVI only gives a general trend, the results obtained using the feature mixing model directly gives a more plausible picture of the vegetation of the corresponding terrain
