A seismic lattice defines the seismic trace organization during a 3D acquisition. It is represented by a regular IJ 2D grid (Figure 13.1-1) where each node corresponds to one final common midpoint (CMP) gather.

At the feature level, the dimensions of seismic lattices are usually oriented along an inline axis and a crossline axis. The indexing of these two dimensions must be regularly incremented along each axis. This is the only constraint; for example, there is no constraint that the origin indices must begin at 0,0.
