<p>A method for sonic analyzation on-line and in real time or off-line in post processing of a topographic representation of a seafloor to provide the latitude and longitude of an object producing a corresponding anomaly (32) appearance identified in a topographic representation generated from a side scan sonar tow fish includes in the on-line, real time analyzation the steps of sequentially touching the tip of the sonic digitizer stylus to a point on the line (24) representation of the seafloor laterally opposite the appearance of the anomaly appearance (36); and, if length is desired, to the top and bottom edges of the anomaly appearance.</p> |
