Talk:GPS Exchange Format

mime type?

What is its mime type? Been looking and cant find it. --George Drummond 19:26, 2 February 2007 (UTC)

See MIME#Content-Type. --Mircea.Vutcovici 19:25, 23 September 2007 (UTC)

More extensive explanation

I noticed hat the French version of this article is much more extensive.
In particular, the English version makes little relation between track and <trk> etc..., that is between the explanation and the format in general. For that reason, I have modified the "data types" paragraph as in here and I propose to replace it.
I would prefer another title than "Data types" such as "Description", to your liking too.
Any comment, especially text replacement, including better English, is welcome before doing the update.
Cheers. --A Pirard (talk) 16:31, 25 September 2013 (UTC)

EXIF

For which reason is the Exchangeable image file format linked in the see also section? --Abdull 12:38, 29 March 2007 (UTC)

EXIF information and GPX could be used to create geodata. For example you could make a photo of a place. Based on the time when the photo was took and the track of the GPS you will know the place where the photo was made. If you make a map with a GPS, the street name or other geodata information can be recorded by making photos without taking notes. Can someone explain this more clear and update the article? --Mircea.Vutcovici 19:34, 23 September 2007 (UTC)

Datum of lat/long

lat/lon elements uses the WGS84 datum, as said in http://www.topografix.com/GPX/1/1/gpx.xsd. I think it's important information to add to the page... —Preceding unsigned comment added by Pengi (talk • contribs) 09:36, 24 September 2007 (UTC)

Native Support/methods of use

This article lacks any mention at all of how the end-user uses this data and what, if any, embedded devices natively support it or use formats that this data can be converted into. Flagged for expansion. MrZaius^talk 16:40, 20 March 2008 (UTC)

I know that some Garmin GPS devices have native support for eXchange Format data. http://developer.garmin.com/web-device/garmin-communicator-plugin/device-support-matrix/ has a list. Garmin's "MapSource" Windows application can read/write GPS eXchange Format data files plus several other format. (no source for that other than it's implied in the bug/fix list at http://www8.garmin.com/support/download_details.jsp?id=209) --Marc Kupper|talk 01:50, 2 March 2012 (UTC)

GPX has nothing to do with "data transfer"

Sorry but the title is wrongly described. GPX has nothing to do with data transfer. GPX is a XML file format to describe data - NOT TO TRANSFER IT. I couldn't figure out how to change the title, or I would have. —Preceding unsigned comment added by 141.189.251.1 (talk) 12:57, 17 June 2008 (UTC)

Remove external links section?

I propose that the external links section is removed. The only two useful links in there are the GPX home page and (tenuously) openstreetmap, but both of those are also listed higher up in the page. The rest is a random selection of programs, libraries and websites that use GPX, of which there are thousands. Thrapper (talk) 17:26, 27 October 2009 (UTC)

Your logic is sound, young grasshopper. —Preceding unsigned comment added by 70.91.201.209 (talk) 18:59, 5 November 2009 (UTC)

<ele>?

What is the "<ele>4.46</ele>" in the "Sample GPX Document" good for? -- 84.132.98.154 (talk) 07:14, 2 January 2010 (UTC)

It's for elevation. In this case, less than 5 metres above sea level. There's more information about the spec at the given link. Thrapper (talk) 00:38, 21 January 2010 (UTC)

Maps

As far as I understand the gpx format also includes maps that can loaded into GPS devices but the article seems to have precious little information about this.150.227.15.253 (talk) 08:54, 29 July 2019 (UTC)

News to me. Do you have any reliable sources? Barte (talk) 13:22, 29 July 2019 (UTC)

Confusing graphic

I really don't understand the graphic included in the article, so I made my own, based on my understanding of the file format and would like to suggest to replace the old one with it. Corrections or other improvement notes are very welcome. Toebs (talk) 17:20, 10 April 2025 (UTC)

Yours makes more sense than the current one. In yours, someone starts at the top of the map and plans to follow the pink route. They put the route points into their device. They set off to follow the pink route and actually follow the blue route. Their device captures a series of track points. Between track points 6 and 7 they lose their GPS signal (put their device in their rucksack?) but they must have successfully carried on along the pink route until they regain their signal and start segment 2. The article would need updating to discuss routepoints and trackpoints, and perhaps discuss waypoints. Would it add too much complexity to add a waypoint to your diagram? I think it would show where the user planned the pink route, followed the blue route, and then noticed something interesting (or navigationally important, such as a bridge across a stream) along the way. I’d also put start and end at the top and bottom of the routes. Northernhenge (talk) 19:08, 10 April 2025 (UTC)

Thanks for your input, I edited the article to hopefully clear the data types section up a bit and also updated my graphic to include your proposed changes. Toebs (talk) 15:10, 11 April 2025 (UTC)

Makes sense :) --Northernhenge (talk) 16:05, 11 April 2025 (UTC)
