When planning lines for a Sidescan Survey there is a tradeoff between time and data. To overlap the data so the nadir area from one pass is covered by the next lane requires more time than if the purpose is to ensure there is complete coverage.

100% coverage: At 100 meter range scale, line spacing would be set for 160 meters. This provides a 20 meter off-track error while surveying.

200% coverage: This survey plan ensures that the bottom is covered twice by the Sidescan, covering the nadir region with the second line pass
