Displaying the grid
If you select this box, the grid of lat / lon coordinates are displayed on
charts.
Displaying chart outlines
If you select this box, the contours of available charts are displayed.
Antemeridian
Select the box to choose a chart display centered on the antemeridian
(longitude 180¡) which replaces the display centered on the Greenwich (longitude 0¡)
meridian.
The positioning icon
You can specify the length of your ship (you are reminded that size of the
icon displayed on the chart is proportional to the length of the ship and the
scale of the chart), the type of icon and its minimum size.
Note: when the ship icon is scaled to size (i.e. when a larger chart scale is being
used and the length of the vessel is indicated) its outline contour is two
pixels wide, whereas when the icon is displayed at its minimum size (small chart
scale) its contour is just one pixel wide.
You can specify the diameter of the safety circle (depending on the precision
of your positioner); in this case a corresponding circle is shown around the
vessel icon.
