MONITORING IRON OXIDE, CLAY MINERAL AND FERROUS MINERAL USING LANDSAT MULTISPECTRAL IMAGE
Le Quy Don Technical University, Hanoi, Vietnam
To evaluate the conventional methods for mapping iron oxide, clay and ferrous mineral by using LANDSAT 7 ETM+ image in Thai Nguyen area is prime target of our study. We used band ratio methods for determining the areas in rich and poor mineral composite content. Resulting mineral composite index maps are summarized in nine classes by using ‘natural breaks’ classification method in GIS.
Keywords: remote sensing, iron oxide, clay mineral, ferrous mineral, band ratio.
