SPECTRAL BEHAVIOR AND SPECTRAL SEPARABILITY OF ERODED LANDS USING MULTISENSOR DATA

A sound knowledge of the spectral behaviour of any feature or phenomen on helps to establish its spectral response pattern, which ultimately allows it to be detected and delineated using spectral measurements ma de by multispectral sensors aboard different platforms. The spectral b ehaviour of eroded lands and associated features was studied in part o f the Bijapur District of Karnataka State using multispectral measurem ents made by the Landsat-multispectral scanner system (MSS) and themat ic mapper (TM), and SPOT-HRV multispectral linear array (MLA) sensors under near-identical illumination and atmospheric conditions. The spec tral separability of different categories of eroded lands was also stu died using scattergrams and divergence analysis. (C) 1997 by John Wile y & Sons, Ltd.
