The use of intensity-hue-saturation transformation of Landsat-5 thematic mapper data for burned land mapping.

Abstract

Several techniques have been developed to detect and map burned areas using Landsat Thematic Mapper data, ranging from simple ones, such as visual analysis, to more complex, such as spectral mixture analysis. However, the Intensity-HueSaturation transformation, a method mainly used for merging multiresolution and multispectral data and for contmststretching applications, has never been applied. In this study, a method is resented bv which transforming the RGB values of a three-ch;mnel comiosite to IHS Galues, ;he mapping of areas affected by forest fires can be easily achieved. Specifically, the hue component of two RGB color composites, consisting of TM7-TM4-TM1 and TM4-TM7-TMI, respectively, proved to be very useful in mapping of burned areas.
