Full coverage boundary of 3D seismic survey system

In order to explain the disparity in the results of full coverage boundary between 3-D seismic fasciculate survey system designed by comprehensive plan act and professional design software of MESA Expert, the paper discusses the specific steps as follow:Firstly, the bin is carefully separated into longitudinal bin size and transverse bin size in accordance with the concepts of bin and coverage number; Secondly, the reasons of the disparity between two kinds of designing methods are worked out through the specific analysis of longitudinal survey system and transverse survey system; Finally, full coverage boundary results designed by comprehensive plan act are adopted. What's more, the paper revises and makes the results as exact full coverage boundary.
