Abstract
A method for steering a marine seismic acquisition system by determining a steering point associated with towed seismic equipment is described. Coverage boundaries for a current line in a seismic survey and for an already acquired adjacent line in the seismic survey are computed. Cross-line distances between the coverage boundary for the current line and the coverage boundary for the adjacent line are computed based on a set of specifications for the seismic survey. A steering point associated with towed seismic equipment is determined based on the computed cross-line distances. A least one steering command for a steering element in the marine seismic acquisition system is generated based on the determined steering point.
