The present study deals with the application of spectral signatures, obtained from multispectral satellite images, in order to obtain regression estimates for the timber volume per unit area. The studies were carried out in South African <i>Eucalyptus</i> plantations. The greyscale values, recovered from sampling points based on 3 x 3 pixels, were satisfactorily closely correlated with the target variable. Cost-efficiency calculations indicated that two-and multiphase sampling with the aid of satellite images are an attractive alternative for traditional terrestric measurements. Further research is required.
