Hyperspectral remote sensing data has the characteristic of combining both image data and spectral data into one data set, each pixel of a hyperspectral image an entire spectrum (consisting of numerous contiguous, narrow spectral bands) is present. Compared with conventional multi-spectral remote sensing data, hyperspectral remote sensing data can be more useful for the identification and classification of surface Materials. In this paper, the author classified the coastal area using hyperspectral remote sensing data, and further more, succeeded in extraction of sand beach surface information related to bearing capacity characteristic.
