Study of Optional Bands Combination of Landsat Imagery for Extracting Information of Ice Shelves

Abstract:

For the purpose of extracting the information of ice shelves, the statistical analysis of TM, ETM+ and Landsat8 OLI imagery of the typical area at the southwest corner of Wilkins Ice Shelf is conducted. Basic statistics of single bands were extracted and the correlation coefficients, joint entropy as well as the Optimum Index Factor among multiple bands were calculated. The results of experiments as well as the characteristics of spectrum characteristics of the surface features were taken into consideration comprehensively and the optional bands combinations were investigated. Results show that for TM and ETM + imagery, the combination of band 2, 3 and 4 is the optional bands combination. For L8 OLI imagery, the combination of band 3, 4 and 5 is the optional bands combination. In these two kinds of combinations, the images contain abundant information and moderate brightness. The features are more obvious to distinguish.
