Abstract:

The survey line layout is the primary content of the technique design in marine magnetic survey. The problems of the survey line layout in marine magnetic survey of our country have been analyzed. The evaluating method of the survey line layout with the interpolation precision between the adjacent lines has been put forward. The result show that the interpolation precision between the adjacent survey lines can be applied in the analyzing the affect of the survey line layout to the survey and can be used to evaluate the rationality of the survey line layout, which can provide the basis of the optimizing of the survey line layout.

Key words: marine magnetic survey, survey line layout, magnetic anomaly map, interpolation precision
