Map Page
The Map Page provides a comprehensive display of electronic
cartography, plotting, and navigational data. When using the unit
with optional BlueChart or MapSource data, the Map Page shows
your boat on a digital chart, complete with geographic names, map
items, navaids, and a host of other chart features. It also plots your
track and shows any routes and waypoints you create. The map
pointer allows you pan and scroll to other map areas, determine the
distance and bearing to a location, and perform various route and
waypoint functions.
When the map pointer is active, an additional data window appears
at the top of the map to indicate the location, range, and bearing to
the map pointer, a selected waypoint, or map item. The map zoom
range shown at the lower-right corner of the Map.
The Zoom
RANGE Down and RANGE Up keys combined with
the
ROCKER
, allow you select zoom ranges and move the map
pointer. Two basic map operating modes, Position Mode and Pan
Mode, determine what cartography is shown on the Map Page.
Position Mode moves the cartography to keep the present position
marker within the screen area. Pan Mode moves the cartography to
keep the map pointer within the screen area.
The GPSMAP 392/398/492/498 starts in Position Mode, with your
location centered on the Map Page. When sufficient map coverage
is not available to keep your location centered, the position triangle
moves toward the edge of the screen.
Pan Mode starts when the
ROCKER is pressed. The map pointer
is moved over the Map Page using the ROCKER . When the map
pointer reaches the edge of the screen, the map scrolls forward
under the map pointer.
