Abstract
Different topographic correction methods for Landsat ETM-image were compared. Corrected images were compared using land cover classification and estimation of forest inventory variables. Also the effect of the amount of vegetation to the correction coefficients were studied. Generally the best correction methods were Ekstrand and C-correction when their coefficients were determined by stratifying data according to the amount of vegetation.
