Viewing Cartography - Humminbird 598ci Operation Manual

Viewing Cartography

In the Chart or Combo Views, there are several cartography-related functions
that you can access using various keys.
Chart View with Cursor Present, shown with
Optional-Purchase Navionics® Cartography
Zooming: Press the Plus (+) key to Zoom In and the Minus (–) key to Zoom Out to
see the cartography at different magnification levels. The zoom level is indicated
on the left side of the display. If you zoom in beyond the available chart data, the
display will go into Overzoom mode whereby the last available chart data is
amplified to reflect the level selected. If you zoom in so far that no cartography is
available, a lat/long grid will be drawn instead. Zooming is also influenced by the
Auto Zoom and Auto Range settings. See Chart Menu Tab: Auto Zoom and Auto
Range for more information.
Decluttered Waypoints: When two or more waypoints overlap, or are displayed
close together on a chart view, the screen will automatically declutter—waypoint
names will shorten and the waypoint icons will change into small blue icons.
To view a Decluttered Waypoint at full size, use the 4-WAY Cursor Control key to
move the cursor onto a decluttered waypoint icon. When the cursor snaps onto
the icon, the full-size waypoint name and icon will be displayed. You can also press
the + ZOOM key until you can see the individual waypoints on the screen.
Chart Info: Press the CHECK/INFO key to get detailed information about the chart.
If the cursor is active, you will see information about the chart objects located near
the cursor.

Panning: Use the 4-WAY Cursor
Control key to move the chart around
on the display in the direction of the
key being pressed. When you do this,
a bull's eye cursor is drawn at the
center of the screen and is linked to
the boat by a gray line, even if the
boat is off the screen. At the same
time, the temperature and speed
boxes in the lower left corner are
replaced with the distance and
bearing from the boat to the cursor
position and the latitude/longitude
coordinates of the cursor.
