==Vertical slices==

As it arrives on tape from the processor, 3-D seismic data are organized into lines composed of traces. In the computer these are all merged into a dense cube of data. The data cube can be sectioned, or sliced, in several ways. Vertical cuts through the data cube are called '''lines''' or '''sections'''. For marine surveys, [[in-line]] is the direction of boat movement (parallel to receivers) and [[cross-line]] is perpendicular to boat movement. For land surveys, there is no uniform definition of in-line and cross-line. A vertical section that is neither inline nor cross-line is an arbitrary line and may be very irregular in map view as needed to pass through locations of interest.
