Modeling the Accuracy of Multispectral Remote Sensing Methods in Determining the Density of Forest Green Phytomass

Abstract

A general approach is proposed for determining the quantity of green phytomass of different classes of forest vegetation on the basis of multispectral remote sensing data without invoking any additional information on the investigated objects. The basis for a solution of this problem is a functional description of the solar radiation emanating from a forest community as a function of the characteristic properties of the studied forest ecosystems, as well as sun and instrument viewing angles from space at medium to high spatial resolution.
