- •
Over 1100 hyperspectral measurements, vegetation cover and biomass (AGB) records.
- •
Random Forests based hyper- and multispectral estimation of vegetation cover and AGB.
- •
Multispectral information is sufficient to estimate vegetation cover and AGB.
- •
Regionalization of vegetation cover and AGB using 7 high resolution satellite scenes.
- •
The results will help to monitor pasture degradation on the Qinghai-Tibet Plateau.
