Hi, I succeeded writing a GPX export feature in my cave survey freeware so that users can export the cave line plot into their GPS and walk "over" their cave...
I apologize for using this mailing list for what should be a private message to Garmin's development team, but they don't make it easy to contact them. If...
Hello, This is my first message on this list, so first I should introduce myself: my name is Carlos Tejo, and I'm a student at University of Oviedo. I am going...
Hello, ... There are already GPX extensions for closed shapes. There isn't an explicit way to associate a <wpt> element with a <polyline>, but you could...
Hello, ... Thanks for your example. You have said that it is not way to associate a <wpt> element to a <polyline>. Why we cannot add the polylie inside the...
Hello, ... That's certainly possible, although doing it that way would mean that 99% of the programs out there wouldn't recognize the polyline (because they'd...
Carlos--have you considered using PostGIS, or one of the spatial formats that handles tagging of all attribute types? I would think that even a Shapefile...
Hello to everyone :) I'm developing a software for academic purpose which needs to import GPX or more exactly part of GPX files. In any case I need to parse...
... Can you remove things from the GPX file until you get a successful match ? Or, perhaps start the other way: remove everything but the head and tail, and...
Yeah, KML could work too--although there are some very convoluted (but legal) KML constructs that I would hate to have to parse. We don't really have enough...
I'd be very surprised to find any GPS devices that can handle KML. It is an extremely rich format. My recommendation, as a GIS practitioner and developer, is...
I tried to send the e-mail in to info2004 at topografix.com for adding MyWay Navigator product in to supporting SW list, but the mail address seems not to be...
Hi all, Is there some way of encoding turn by turn instructions into a .gpx file without using some sort of software like Garmin's Mapsource to plan the route?...
If you are asking how to represent turns in GPX, my understanding is that each route point should be considered a turn point. While there is no specific XML...
... Agreed. The OP says they used <rte> and <rtept> and that seems reasonable to me. The ony problem with this approach is that you can't import such points...
Hi All, I have come across an interesting situation when converting a log of NMEA sentences to GPX. Firstly, the NMEA sentences are saved in a CSV file as per...
... First, take a look at the GPX file with a text editor. Are there timecodes in there associated with each point ? If not, then Mapsource is not seeing any...
Hi Simon, Yes, each point does have a timestamp and the times are reasonable. For example, the speeds only jump around in smallish amounts, but enough to show...
I'm developing a geotagging app of sorts that can read GPX files. I've noticed a couple GPX exporters (gpsbabel and Garmin's "Bobcat") that will take a...
... "ACTIVE LOG" and ... <trkseg>: Can't speak for Bobcat, but I can speak pretty authoritatively for GPSBabel. Disclosure: I am the Chief Babel Head. ... day...
natevw, I agree with you: A trkseg should not be turned into a new track resulting in tons of tracks. I also think that trkseg is a very reasonable construct,...
... I agree. That would seem to be exactly the purpose of having trksegs in the GPX format. Segments could be used for many different purposes, not only GPS...
... So I got interested and went back to the GPX documentation: <http://www.topografix.com/gpx/1/1/#type_trksegType> "A Track Segment holds a list of Track...
Hello, ... Read Martin's email again - every spatial format contains the concept of a multi polyline - a single object that contains multiple lines. There are...
... As far as how it maps to other GPS related formats, I will defer to your experience there. But as other posters have mentioned, the concept of one item...
