Using 10m resolution satellite images under ideal weather conditions, we can detect and observe waves on the sea surfaceWe consider the regional wave field as a signal from which we can extract the wavelength, frequency and wave direction. Within the depth of closure these parameters correspond not only to the weather conditions, but also vitally to the seabed morphology.  

2D Fast Fourier Transform is a widely used transformation to access these desired parameters from waves. Wavelength and wave direction information is extracted through this process, and combined with the spatial variation of the data, used to deduce the underlying morphology.
