Abstract

A method for operating a computer to reduce the memory needed to store seismic data. The seismic measurements are first organized into a multi-dimensional data array. The multi-dimensional data array is than sub-band coded to form a coded data array by applying a one-dimensional transformation corresponding to each dimension of the data array to that dimension of the data array. The transformation is determined by the frequency content of the corresponding dimension of the data array. The sub-band coded data array is then quantized to provide a compacted data array.
