IV - BURNED LAND MAPPING, FIRE SEVERITY DETERMINATION, AND VEGETATION RECOVERY ASSESSMENT<br />

For this study case, in c<strong>on</strong>clusi<strong>on</strong>, the multiple thresholding with fixed values<br />

seems to be the best classificati<strong>on</strong> method for this applicati<strong>on</strong>: it<br />

requires relatively fast processing, does not need either ground validati<strong>on</strong><br />

or operators’ great expertise and gives fairly accurate results (especially<br />

when images with a good temporal coverage are used).<br />
