View Orientation; Viewing Cartography - Humminbird 800 series Operation Manual

View Orientation

Both Chart and Chart Combo Views allow you to choose the orientation of
the view (see Navigation Menu Tab: Chart Orientation). In each orientation,
the view pans automatically so that the boat is always centered on the
display. To see more of the view when the boat is traveling at the speed you
set, see Chart Menu Tab: Vessel Offset and Offset Speed.
• North-Up: True North is shown at the top of the display. Objects
located to the north of the boat are drawn above the boat.
• Heading-Up: The boat's current heading points up, and the chart
rotates around the vessel so that the vessel always points up on the
view.
• Course-Up: During navigation, the projected course is shown at the top
of the view. Objects ahead of the boat are drawn above the boat. When
the boat is not navigating, the course-up reference is provided by the
COG (course over ground) calculation. Also, to display the north icon on
the view, see Navigation Menu Tab: North-Up Indicator.
North-Up Icon: If it is turned on, the North-Up Icon displays the direction of
True North. It also displays the Chart Orientation, and the icon will change
as the orientation and the data source change (see Navigation Menu Tab:
North-Up Indicator).
When the boat is stationary, it is drawn as a circle.
When the boat is in motion, it takes on a boat shape,
pointed in the direction of motion (always up in the
Course-Up orientation).

Viewing Cartography

In the Chart and Chart Combo Views, there are several cartography-related
functions that you can access using various keys.
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, a cursor
dialog box is displayed at the top of the screen with the distance and bearing
from the boat to the cursor position and the latitude/longitude coordinates
of the cursor. When the cursor is active on the display, you can also use the
4-WAY Cursor Control key to move the cursor diagonally.
