Claim:
1. A method, performed in at least one processor, for generating a similarity indicator between seismic datasets acquired over a survey area, said method comprising: obtaining a first seismic dataset collected at a first time and a second seismic dataset collected at a second time; processing with the at least one processor said first seismic dataset and said second seismic dataset as first and second images, with pixels in said first and second images being associated with reflection points; calculating a first image registration metric based on said first image and said second image; calculating a second image registration metric based on one of said first image and said second image; generating a similarity indicator between said first seismic dataset and said second seismic dataset using said first and second image registration metrics; and reshooting at one or more positions in the survey area determined based on the similarity indicator.
