A course deviation indicator (CDI) is provided to the pilot(s) to show both graphically and numerically their perpendicular distance from the current desired flight line. Real-time coverage tracking is provided through a plan progress window that provides a map of the survey area including flight lines. When the aircraft passes through a survey area while the LIDAR is activated, the resulting laser swath traced on the ground is drawn on a plan progress display.
