    Abstract: Method and system for generating a full acquisition path for a marine seismic acquisition system. The method includes receiving survey area information about a survey area to be seismically surveyed; selecting a radius (R) and a length (L) of a lace; selecting an overlap distance (OL) between first and second lanes; generating the full acquisition path by repeating the lace along a first lead line inside the first lane and along a second lead line inside the second lane and replicating the first and second lanes until the entire survey area is covered with laces; and sending the full acquisition path to a streamer vessel for performing the seismic survey.

    Abstract: Methods and systems for similarity indicator calculation associated with seismic data acquisition are described. A similarity indicator value can, for example, be based on a normalized partitioned intensity uniformity (PIU) metric. In another aspect, shot imprints are compared by mapping a base (reference) shot imprint onto a current sample of a shot imprint before calculating the similarity indicator value. The similarity indicator value is associated with the shot imprint location used in the calculation and allows re-shooting of only the areas where an insufficient quality of shot data is detected based on a preconfigured threshold value for the similarity indicator.
