Bird’s Eye View
Bird's Eye View -
This view shows a 3-D, perspective view of the track and the
chart’s land contour from a point above and behind the boat (the eye point). As the
boat turns, the eye point moves to follow the boat.
When you press the 4-WAY Cursor key in the
Bird’s Eye View
, the position of the
eye point will shift. This allows you to move and turn the eye point so that you can
look off to the sides, or even behind the boat. Pressing the RIGHT or LEFT arrow
keys on the 4-WAY Cursor key turns the eye point right or left, while pressing
the UP arrow key moves the eye point forward, and pressing the DOWN arrow
key moves the eye point backward.
Pressing the EXIT key moves the eye point back to its original position behind
and above the boat.
