Mapping surface features from stacked seismic data

A non-transitory computer-readable storage medium storing instructions executable by a computer system, the instructions when executed by the computer system cause the computer system to:

• receive a three-dimensional (3D) seismic cube comprising seismic reflectivity data obtained at a geographical location;
• generate a vertical analysis window of the 3D seismic cube;
• extract a second 3D seismic cube from the seismic reflectivity data based on the vertical analysis window, the second 3D seismic cube having a plurality of vertical amplitude traces associated with the seismic reflectivity data;
• generate 3D data comprising a plurality of frequency traces from the plurality of vertical amplitude traces using a domain transform;
• and
• generate a two-dimensional (2D) map from the 3D data, the 2D map representing geographical features of the geographical location.
