Fractional vegetation cover
Abstract
Fractional vegetation cover (FVC) is an important biophysical parameter describing the Earth's surface system. This chapter summarizes various methods used for the field measurement and remote sensing retrieval of FVC, including visual estimation, sampling and the use of optical measuring instruments, regression modeling, mixed pixel decomposition, and machine learning methods. Some frequently used methods are described in detail, and actual examples and discussions are given in the section describing field measurement. Then, the principal remote sensing–based FVC products and algorithms are briefly introduced, and the temporal and spatial variation of estimated FVC by using remote sensing ...
