Measure Distance and Area
Use the measurement tool to measure the distance of
a line or the perimeter and area of a polygon on the map.
To measure distance
From the Map Page, go to MENU > Measure Distance.
 Use the arrow keypad to move the cursor to the area
on the map where you want to place the first point of
the line or polygon and press ENTER to place the first
point. Repeat for each point.
 To undo a point, press QUIT.
 To make a polygon, you must close the shape. Place
the last point on top of the first point by hovering the
cursor over the start location and pressing ENTER to
snap the point and close the polygon.
While you are measuring distance, the pan location infor-
mation that displays in the top right corner of the screen
changes to display the heading from the last measurement
node to your current GPS location, the leg distance, and
the total distance from the last measurement node to
the first measurement node. Once you close a polygon,
it displays the area.
You can also measure area using a track. See Calculating
the Area of a Track on page 54.
