Implementation of Landsat 7 ETM+ principal polar spectral indices based on EO-1 Hyperion wavebands selection

Principal Polar Spectral (PPS) is a high-order index set that developed on Landsat 7 ETM+ which has advantages in observing the soil and vegetation cover. The purpose of this study is to determine the most appropriate Hyperspectral EO-1 Hyperion wavebands for modeling PPS Indices, which provide higher spectral complexity compared to Landsat 7 ETM+. Despite of larger data dimensions compared with EO-1 Hyperion single and region correlation as well as Landsat 7 ETM+, the result showed that 163 EO-1 Hyperion bands using Spectral Focus located at (1.5, 1.5) provide the most idealized measurement results with relatively lower brightness and broader greenness variety in the images, with R
