GPX EDITOR VS BASECAMP SOFTWARE
If you upload the tracks from your GPS into Garmin Basecamp, the software allows you to do some very limited editing of your track files before you publish them. If you're going to use your GS the way the designers intended and really take the road less traveled to adventure, you'll end up getting pretty proficient with loading and using track data and maybe you'll take some adventures and publish your own track that you took so that others can enjoy your ride. You can see that it also included notes about waypoints for turns, gas, food, lodging, etc. If you look at the screen shot I posted in my first post, all of that data on the map is from a single GPX file for the Mid-Atlantic BDR. If you go to the source of a publisher, for example, you'll find that the adventure rides they publish will be in the form of a GPX file that includes a track per suggested day of riding and POIs along the way. GPX files are a typical way to export and share GPS information and can include tracks as well as Points of Interest (POI). Forest roads change, land owners change their minds about traffic through their land, roads get washed out - by hey, that's why they call it an adventure. Now, that doesn't insure that it's passable or still open for travel. It's said that if you're following a published track that you can be sure that someone has ridden that exact way to follow before. It's for that reason that they are very popular among adventure riders that will spend time in places not typically used by the routing algorithms of GPS units. They are typically created by taking the breadcrumb points (tracks) from the GPS of someone that previous created and rode that particular way to get from here to there. Tracks are used when it's very important that you exactly follow an intended way to get from here to there. BMW Nav units have configurations that tell the GPS your preferences (fastest time, shortest route, include dirt roads or not, etc) but it's the GPS algorithm that determines the path you'll take to get to your destination. This way if the route is starting to reroute or make a false turn you will see it and can decide to just follow the track instead.Īs mentioned in this web page, routes are preferred when you want to reach your destination and you're willing to leave it up to the GPS to determine how you get there. It is possible to use both the track (colored line overlaid onto the map) and the route. Otherwise you may get the dreaded “make a legal uturn” or worse, it will make you exit the interstate and go back the opposite lane because this is where the next waypoint is. But it’s crucial that you use the same map for planning and routing and that no waypoints are slightly off the highway, which can happen when an imported GPX doesn’t exactly line up with the highway information of the map. Knowing that a turn is half a mile ahead and the name of the road is preferable compared to tracks where you have to guess distance from the map and based on your zoom level. Routes are of course nice when you stay on pavement and go fast. Tracks are also essential when sections of a road are not known to the GPS map. I like to navigate with tracks because the track is cast in stone by the time I upload it from Basecamp and there won’t be any funny rerouting business that you can get with routes. Some devices can recognize the direction from one point to the next and give very crude directional voice information but without any reference to actual road names etc. It can be imported as is into most GPS devices and will just display as a line (the connection between the GPS points being determined by their order in the list). This is why it is independent of any map product. You can open the list with any text editor to check it out.
