When you select a track to navigate with the newer generation units like the GPSMAP 62, a route will be created and displayed on the GPS. Waypoints are automatically generated for major high and low elevation points and the start and finish points. These and any user waypoints along the track are added to the route points along the route. This allows you to use the Data fields to provide you with information regarding, the distance to, time en route, arrival time, or name of the next point (high point, low point, or waypoint) or destination.
The 62 series can hold 200 tracks with 10,000 track points each. For a total of 2 million possible track points. Filtering down a track will reduce its number of points, but it also affects the shape of the track as displayed on the gps’s screen. A 100 mile track with 50 points is less detailed in shape than a 100 mile track with 10,000 points.
There’s also the option to enable a single track or multiple tracks to ‘Show on Map’. You can set the track colors to make it easier to see and distinguish between them. When following a track there’s no written rule that says you can’t turn ‘Tracking’ on and display your current movements in regards to the track your following. This way you know where you’re at in regards to the track.
