This paper describes potential application of geostatistic method in predicting stand volume based on satellite images for disturbed natural forests in the Central Highlands of Vietnam. The study tested different image data such as original 4-band combination of SPOT 5, Principle Component (PCs) and Normalized Difference Vegetation Index (NDVI). The independent field data was then used to validate the results using Root Mean Squared Error (RMSEs) ad Mean Average Error (MAEs) as the criteria of accuracy assessment. The result shows that presence of all band SPOT 5 represented as the best one compared to others.
