The Fourier waveform analysis algorithm is applied to the computer processing of spectral reflectance data. The spectra for different landcovers are decomposed into wave components of different orders

which have definite features and bear useful information contents. The amplitude and phase of each wave component solely determine its contribution to the overall waveform of spectra. The study reveals that the Fourier waveform analysis algorithm is capable of processing the hyperspectral image data acquired by imaging spectrometers such as AIS andAVIRIS.
