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

Abstract

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 R2 value of 0.988 and RMSE value of 2.256.
