2.9 Selecting Track Plotting
Interval
The plotting interval determines both how the
track will be reconstructed on the display and
track storage time. A shorter interval provides
more accurate reconstruction of track line,
however total storage time is reduced. The
plotting interval can be selected by time or
distance. Plotting by distance offers the ad-
vantage that the track is not stored when the
vessel is anchored.
