Shaded relief seismic attribute

Shaded relief is employed throughout geophysics to display digital data as illuminated apparent topography. Such displays facilitate geologic understanding because apparent topography often suggests true geology. First developed for elevation data (Batson et al., 1975), shaded relief has long been used with gravity and magnetic data (Paterson and Reeves, 1985; Kowalik and Glenn, 1987), it is a natural product of synthetic aperture radar and side-scan sonar, and it is routinely applied to interpreted seismic horizons (Hoetz and Watters, 1992).
