Map Page
The GPSMAP 172/172C’s Map Page combines digital chartplotting with a user-selectable display
of navigation data and a built-in worldwide database. It is also the page you use most to create and
edit waypoints and routes. Before we take off on our practice route, let’s take a brief look at its various
features and displays.
The map display shows your “boat” as a triangle marker on an electronically generated chart.
Geographic names, roads, markers and buoys that are provided by the optional BlueChart or MapSource
data are also shown. It also displays your track, routes and nearby waypoints. An on-screen cursor
lets you pan to other map areas, determine the range and bearing to a position, and perform various
waypoint and route functions.
The data window, located at the top of the page, provides a user-selectable display of various naviga
-
tion data, including speed over ground, distance to the next navigation point, compass ribbon and
current position coordinates. The current map scale setting is located at the bottom right of the page.
