1. A computer implemented method of evaluating seismic data, comprising: receiving, by an input interface of a computer from a second computer via a computer network, a set of seismic signal traces corresponding to seismic volume; applying, by a processor of the computer a wavelet transformation to the set of signal traces to generate transformed signals at each of a plurality of scales; for each of the scales, determining, by the processor, scale dependent coherence information indicative of a coherence of the transformed signals at the respective scale; combining,rocessor, the scale dependent coherence information to generate combined information; and outputting, by the processor to a display unit of the computer, seismic attribute information based on the combined information for display by the display unit of the computer.
