MapSource Appends a "1" to waypoint names??

    So I take a GDB file with waypoints and routes and export or "save as" to a GPX file. If I then open that file, the waypoint names are all correct on the list, but if you open a route, all of the "via" points now have a "1" appended to the name. For example, HOME becomes HOME1.

    Anyone know what's up with this?

    What GPS are you using?

    No GPS involved, just MapSource.

    This is behavior typical of BaseCamp - it can't handle duplicate Waypoint names. I've never seen MapSource do this on it's own. Did you create the GDB file or was it given to you?

    When you say "take" where did you get it from?

    Are you saying you open (MapSource) the .gdb file and it only has single waypoints, then you "save as" .gpx and now it has double Waypints?

    Are you sure the double Waypoints did not come from your GPS? If I download the same waypoint in two routes, like said above Garmin does not like this and gives the exact same waypoint a sufix (1)

    My own creation. Let me clarify a bit. When I open the .gpx version of the file, the waypoints are correctly named and there are no duplicates in the "Waypoints" tab. However, when you select the route properties for a route comprised of some of those waypoints, then select the "via points" tab, all of the points listed there are the waypoint names as in the GDB version, but with a 1 appended to every name.

    I initially thought it had to do with auto-routing using a routable mapset, but tried recreating a route both with and without utilizing a mapset and with autorouting off (use direct routes) but to no avail.

    See my reply above. No, the waypoints are correctly displayed with proper names and no duplicates in the "waypoints" tab. The "1" that I mentioned shows up on every waypoint name in the "via points" tab in the route properties.

    Go figure.

    I think you (or, MapSource) have stumped the panel Dave. I've never seen MapSource do that and I just tried to recreate that condition and could not - using MS v6.16.3.

    You still didn't answer the question, where did you get this .gpx file?

    I just tried it and replicated it.

    I believe your problem is that GPX files treat waypoints (in the tab) and waypoints in a route the same. So, if they are both in the same "pool" of waypoints, they are naturally duplicates of each route waypoint.

    Easy solution is to just use the GDB file. If you want to share the file with GPX users, save it off as a GPX when all your planning is done, and let the other guy worry about it.

    This is a non-problem.

    Well, it's a problem for me, as I wanted to offer a "universal" file for purchasers of our GPS tours. Oh well, Garmin users are 90% or more of our base, so I'm just going back to the "old way" we did it for many years that served us well, and only officially support users with Garmin brand GPS units, and let the other 10% use 3rd party solutions to convert the GDB files to GPX at their own hazard.

    Still, I guess I should try opening the resulting GPX file with a program other than MapSource and see if the waypoint/via point names are appended there. Maybe it's just a MapSource glitch and doesn't happen with other software.

    Thanks for giving it a try and confirming it isn't just my system.

    By the way, using version 6.16.3 of MapSource. Anyhow, anyone else wanting to try replicating this, just create a few waypoints in MS, then create a route using those waypoints. Save file (as GDB) and then also "save as" a .gpx file. Then open the GPX file you created (with MapSource), select the route properties for the route you made, and click on the via points tab. See if the waypoint names you used show with a "1" added to the end. I'd be interested to know if it's always the case that the names are appended with a 1.

    Interesting that MAC could replicate this and I could not even after five route creations.

    So, Dave, why are you sharing Routes with your clients? We only provide Tracks (and Waypoints) for our clients and therefore require them to have a GPS that will show Tracks on the screen. I've never had a problem. Routing sucks - even Direct Routing can have issues between GPS's (like duplicate waypoints).

    Yeah, an update here. I tried several ways doing as I said above, and was not able to replicate the problem myself. I only used 3 to 5 waypoints, but could not get it to do what I'm having a problem with with a file with over 400 waypoints and about 15 routes. I'm going to play with this some more and try to find out what the tipping point or issue is that causes the appendage to occur, but for now a small number of waypoints with one route does not do it on my machine either.

    No problems with our routing using Off Road or direct with Garmin units. As long as auto routing does not occur, which can be controlled locally on the GPS, it's the same results every time. The same is not true for tracks. Exceeding a threshold of (I think 200 or so) causes major problems with Zumo/Nuvi units as they create their own via points and then try to autoroute when navigating a track (converted to route locally). Whereas exceeding the trackpoint limits on the other Garmin units just truncates the route (it ends) at the point where the limit is reached.

    I have found that not all GPS's support turning off Auto Recalculation. The zumo 660/665 can import routes in two ways. One way will convert the Track to a Route but there are no limits to the track point count and again Recalculation has to be set to OFF. The other way to import is via the Off Road Tracks feature. Here tracks have to be filtered to a max of 650 points and you can only have 16 tracks in the library at a time - although unlimited can be held on the µSD Card. I still only provide Tracks since I can filter them to the lowest "common" level usually 500pts. But, it really comes down to what works for your needs.

    All Dual Sport Events that I know of only supply Tracks because of the many problems with Routes. A few people tried Routes in the early days but had many problems. Then one club tried to give ouit 750 point tracks to people with 250 point / track units, again problem. The current standard is 500 point tracks and let people with B&W units ask for special treatment.

    Yes, I like the Off Road Tracks feature of the 660/665. That method pretty much makes them like the rest of the line in terms of being able to accept a track. While there is technically no limit the other way, what happens is if the track exceeds a maximum number of points ( I think the early Zumos were 225 points or so), the unit creates its own via points in substitution for blocks of track points. When that happens, the unit will use auto routing for that segment regardless of whether it's turned on or off. So that can yield some really strange results. The Off Road Tracks is the way to go, and 650 points isn't too bad, though not as good as the 376's 1,000 points. Of course you get to have an unlimited number on the card that you can import, so that's a huge bonus.

    In our GPS tours, we provide waypoints and routes as the main form of navigation, and back it up with tracks. We can do some things that way that can't be done navigating a track alone. However, some folks prefer to follow a track no matter what the caveat, and they can still do that with our tours if they wish. Like you said, it comes down to individual needs and preferences.

    Thanks for helping me troubleshoot this strange phenomenon guys! I'm not giving up yet on figuring out what the particular limitation or event is that causes the problem to arise, and will report here on whatever I find (or don't).
