Value Added Data : Turns the displaying of Value added data On or Off. The Value Added Data (VAD) is a collection
of additional cartographic objects which are not present on the original paper chart (from which
the electronic chart derives). These objects have been obtained from other sources (that C-MAP
believes to be reliable) and then merged to the electronic charts in order to provide more
information useful for the navigation. VAD object can be any cartographic objects and it can be
distinguished from the official-chart-objects from the Quick Info. A dedicated icon is shown on the
Quick Info window to indicate that the object queried is a VAD. The same icon is also shown on
the Full Info page and in addition the extended text Value Added Data is shown on the details of
the VAD object.
Mixing Levels : When the map coverage at the current chart scale does not fill the entire display, the GPS
chartplotter draws the rest of the map using charts from above and below the current scale. When
this function is turned on you will notice the display may redraw 2 to 3 times to show all the details.
Chart Lock (*) : Sets On/Off the Chart Lock option. When Chart Lock is On, the available zoom scales are only
the ones containing cartographic data. Instead when Chart Lock is Off, it is possible to zoom down
into zoom scales not covered by cartographic data after the last available zoom scale covered by
cartographic data. The DSI window, if present, will show “NO CHART”, when an empty level is
entered in the location of map expansion mode.
NOTE(*)
When an empty level is entered, the message “No cartographic coverage” is shown on a window
in a corner of the map display. The warning message is always displayed as long as the current
zoom has no data coverage.
