Getting Paper-Chart-Specific Information
BlueChart cartography also provides paper-chart-specific information, such as chart
publisher, print date, edition date, NTM (Notice to Mariners) correction date, and
scale. Additional notes are available for the paper charts.
To display paper chart-specific information on your Garmin unit:
Place the unit’s cursor on an open area of the chart, and press
ENTER
. A
window displays the chart information and allows you to view additional notes
about the chart area.
BlueChart electronic map detail is presented on a chart-by-chart basis. By providing
paper chart-specific information, you can know exactly from which chart and
scale each displayed feature is digitized. BlueChart electronic charts are a faithful
reproduction of the published official paper charts that mariners are required to carry.
BlueChart data is not seamless. Just like the paper charts from which the data is
derived, you might observe some discontinuity along chart borders, both on your
Garmin unit and on your PC screen in MapSource. For example, if a contour is
present on one chart, and not on the adjacent chart, the BlueChart data is represented
on your Garmin unit or PC screen the same way. Likewise, if adjacent paper charts
that generate BlueChart data are of different scales, you might encounter shaded areas
on the Garmin unit. This can occur at any zoom level and can be easily remedied by
zooming out one or two scale levels on the Garmin unit.
