The present invention relates to a method and system for processing multi-dimensional signal data to determine frequency dependent features therefrom. The multi-dimensional signal data are transformed into space-frequency or time-space-frequency domain, providing second signal data. At predetermined locations of at least a portion of the one of space and time-space of the second signal data a dominant feature corresponding to a largest value of the second signal data is determined. This is followed by the determination of a wave-vector corresponding to the dominant feature at each of the predetermined locations. Finally, a dip map, a frequency map, and an amplitude map are generated using the wave-vectors. The method and system for processing multi-dimensional signal data to determine frequency dependent features therefrom according to the present invention provide a powerful tool for improved and more detailed evaluation of seismic data using dip, frequency, and amplitude maps, resulting in substantially more accurate geophysical surveys.
