Figure 24 Track display options
When the calculated track starts to drift away from the actual track you can reset it by clicking ‘BT Reset’ or
press <Ctrl>-
R on the keyboard. ‘Refresh’ will re-center the map.
If ‘Automatic Center’ is enabled, the map will automatically shift the ship track to the centre if it gets too close
to the edge.
Show heading line: show a straight line that marks the heading according to the GNSS compass.
Show Bottom Track : Show the course as calculated from the bottom-tracking.
Show altimeter: Show the depth at regular intervals.
Allow internet: If a map is not already available on this computer, use the internet connection to collect it.
This could be disabled if the computer is connected to internet over low bandwidth connection.
The last item in the list is a drop-down box where you can select the source of the map. OpenSeaMapHybrid
is usually a good choice, but its servers are sometimes slow and so you might want to switch to Google or
Bing maps.
