The geometrical meaning of the optical characteristic roughness S_N is discussed for the purpose of the use as the scale parameter to estimate the quality of the belt sanded surface. The experiments were carried out under the various grinding conditions by the platen type belt grinder. The ground surface is constructed by the long crested asperities which will be important estimation for quality. The surface roughness parameters such as density of summits, the mean curvature and the mean slope of asperities, the number of peaks and the zero-crossings were calculated by the profile and surface spectral moments. The functional relationship between an S_N and the geometrical roughness parameters were derived statistically by the regression analysis. It was found that an S_N has strongly correlated with the surface invariants of the spectral moment which indicate the curvature and the slope of the asperity at the same time.
