Abstract: The paper described an atmospheric correction method for LANDSAT TMimagery. The dynamic change monitoring of vegetation coverage and the variability of atmo-spheric conditions necessitate the normalization or standardization of satellite imagery. The atmospheric parameters at overpass time were evaluated through interpolation among localmeteorological records. The digital model is used to adjust the variation of illumination parameters with elevation,and to correct for the topographic effect. The corrected imagery canbe suitably used for multitemporal monitoring of renewable resources.
