Abstract

The aim of this study is to estimate above-ground biomass (AGB) in the eastern grassland area of Mongolia applying two machine learning methods, such as the support vector machine (SVM) and random forest (RF), and determine the appropriate method by comparing the results. For this purpose, 21 vegetation indices derived from MODIS data of August 2016 are used. As ground-truth information, reference biomass samples are available from 38 sites of a field survey. To select the appropriate prediction variables, the correlations between the measured biomass in the field and the defined indices are calculated. For further analysis, eight indices with correlation coefficients (r)>0.6 are selected. When the classification results are compared, the RF method demonstrates higher accuracy. Therefore, we can conclude that it can be used efficiently for the estimation of AGB in the selected grassland area of Mongolia.
