Abstract

A new and improved method of forming a color graphic display from seismographic input data is disclosed. The input data sequence is processed to obtain the absolute value of each amplitude value and to select the maximum amplitude value of each oscillation of the waveform. A predetermined number of the largest selected values are classified into a first range of values, the remaining values are scaled according to magnitude into a preset number of ranges and an assignment table is formed with each range being represented by a primary or secondary color. Data corresponding to a first group of ranges of input data is processed to form a representation for a particular color. Similarly, the remaining data groups, corresponding to the remaining ranges, are processed to form a representation of the remaining colors. The image of each representation is sequentially transferred to a sheet and the images are colored with their respective colors, thus producing a color display of the seismic data.
