BlueChart
cartography is "object oriented",meaning that each feature
displayed can be associated with additional information. For example,
when placing the chartplotter’s cursor on a navigational
aid, a window can be displayed with additional information for
the selected navigational aid.
Here
is a good example of what Garmin® means by "Object Oriented".
On the picture to the left, you will notice the cursor has navaid
#13 highlighted.
When
the feature is highlighted, and the ENTER key is pressed, additional
information about the feature is presented, as show in the example
to the right.
Many
different features from the paper charts are represented on the
electronic charts as well. You will notice wrecks, spot soundings,
shading between depth contours with white representing the deep
water, marked traffic lanes, and information about the bottom conditions.
BlueChart
data is not seamless. Just like the paper charts from which the
data is derived, you may observe some discontinuity along chart
borders. For example, if a contour is present on one chart, and
not on the adjacent chart, the BlueChart data will be represented
on your chart-plotter in the same manner. Likewise, if adjacent
paper charts used to generate BlueChart data are of different scales,
you may encounter shaded areas on the chartplotter’s map screen.
This can occur at any zoom level and can be easily remedied by zooming
out one or two scale levels.
To
display paper chart-specific information, place the chartplotter’s
cursor on an open area of the chart (absent of any chart features)
and press ENTER. A window will appear showing the chart information
and allowing you to view any additional notes about the chart area.
Each
paper chart contains a header that explains hazards and other important
information. These notes are also accessible on the BlueChart cartography.
Once the chart info is shown (see above), simply select "Show
Notes".
A
feature of presenting data in a chart-by-chart manner is selecting
only those paper charts that you have on hand or that you want displayed
on the chart-plotter. By default, all available charts will be displayed.
See your chartplotter’s owners manual for specific steps, but
the screen will generally appear as shown at left. From this screen,
use the chartplotter’s on-screen cursor and ENTER key to deselect
(remove the check mark from the box) the individual paper charts
you do not wish to display.
