Note: the button is only displayed if the cartography can be configured (choice of information to be displayed for example). See appendices for the chapter concerned or to the corresponding cartography manual.

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.
