In satellite spectra, though the scale is affected by the intensity of sunstroke, the angle of land inclination, the observation angle of the sensors and so on, the shape is not severely deformed by those effects. Thus, we have developed a spectral shape-dependent analysis utilizing a normalization procedure. By normalizing the apparent reflectances which are estimated from Landsat/TM data using the sum of those between 6 or 4 bands, inevitable topographic and atmospheric effects can be suppressed. The correction algorithm is very simple and timesaving and the suppression of topographic effects is especially effective. Here we show the correction principle and preliminary results.
