WAYPOINT/ROUTE AREA
The bottom section of the screen, below the map area, is used to display information related to up
to 3 user-selected waypoints, or to the currently selected route. You may switch between displaying
Waypoint information and Route information by tapping on the word "Waypoint" or "Route."
WAYPOINT MODES
There are two waypoint modes: Distance Mode and Altitude mode. You may switch between these two
modes by tapping on any of the headers to the right of the "Waypoint" header.
Waypoint Distance Mode
As shown to the right, we have three waypoints: Houston, Dallas, and San Antonio. In each case, the
straight-line distance to the waypoint is displayed (Dist), it's compass bearing (Dir), and the ETA
to arrive at that waypoint at the current speed. The ETA is the time that you'd arrive at the
waypoint if you immediately head towards that waypoint at the current speed. This ETA should be
fairly accurate if you are flying, but will be less-so if you are driving since the road may not be
completely straight or may take you through areas that require you to travel at a lower speed.
Waypoint Altitude Mode
The Waypoint Altitude mode, shown to the right, is often of use when hiking. Waypoints along your
hiking path can be selected and the relative altitude displayed.
The Altitude mode shows, for each waypoint, the altitude of that waypoint (Alt), the bearing to
the waypoint (Dir), and the difference between your current altitude and the altitude of the
waypoint (Dif). The altitude and difference in altitude are expressed in the units of measure
that you selected for "Altitude" (feet or meters). In the "Dif" column, positive numbers indicate
waypoints that have an altitude higher than your current altitude while negative numbers indicate
waypoints that have an altitude lower than your current altitude.
In this example our current altitude is 95 feet above the trailhead waypoint and 1717
and 3939 feet below the Mtn Structure and Mountain Peak waypoints, respectively.
ROUTE MODE
When a route has been defined and selected, the route mode will display information related to
the waypoints along that route.
In the example to the right, we have another 28.8 miles to San Antonio which at our current speed
will take 25 minutes and we'll arrive at 1:25pm. Dallas is 281 miles away, will take 4 hours and
4 minutes to travel to and we'll arrive at about 5:05pm. Finally, our destination is Oklahoma City
which is 470 miles away, will take 6 hours and 48 minutes to travel to, and we'll arrive at about
7:49pm.
Note: The distance to each waypoint along the route is calculated based
on the straight-line distance from your current location to the first waypoint, then as the sum of
the straight-line distances from waypoint to waypoint. Thus as long as you have enough waypoints,
the distance and time estimates should be fairly accurate. It is especially important to place
waypoints at locations where there are significant changes in direction of your route.
Note #2: The calculated time and ETA to each waypoint assumes
that you will be traveling at your current speed the whole time. This is often not accurate
when on cross-country road-trips since you may be traveling at 70mph on the open highway but
have to slow down to 50mph due to traffic in cities. You should consider this when using the
ETA if you'll be traveling through cities or areas where you'll have to travel through
significantly slower.
A maximum of three route waypoints may be displayed. The top-most waypoint displayed is the
next waypoint along the route. The bottom-most waypoint displayed is the last
waypoint along the route. The middle waypoint is the next waypoint that is a major city
beyond the next waypoint--if there are no major cities along the route then the middle waypoint
will display the waypoint that follows sequentially the top-most waypoint.
The idea behind which waypoints are to be displayed is that the top-most waypoint is always the
next waypoint, the next line displays the next major city, and the bottom-most waypoint displays
the last waypoint you plan to travel to today--thus the final waypoint gives you a distance and
an ETA for your final stop.
If you are traveling along a route but will not travel to the end of the route in one day, you may
pick your final waypoint for the day by tapping the name of the last waypoint. You will then be
able to elect to which waypoint along the route you will be traveling to today. In this way the
bottom-most waypoint will reflect the final waypoint you plan to travel to today rather than the
last waypoint along the route.
