GPS GPX output files

[Roy Epperson]

Several years ago (before me moved and stopped riding as much), I developed a Java Applet to read GPX formatted output from GPSs, It provided an interactive plot of the tracks and routes on Google Maps and plotted the elevation vs distance. Never did anything with it as Google's licensing fees for using their API was prohibitive for a non-commercial / hobby project was outrageous for the number of "hits" to do anything useful.

Recently, I got looking for a "project" to do and came across several "open source" GIS APIs and GIS databases which make the project doable. I have a prototype working on my local server using the GPX files I have from the Western US. I'm not ready to host it on my website yet as I've just "proved to myself" that I can get the pieces to do what I want. Time to clean up and "bullet proof" it.

Why my post?

I could use some GPS GPX formatted output to test my plotting, in particular from the Eastern and Southern hemispheres. I'm sure I could Google Maps or MapQuest to create some routes and convert them to GPX format, else elevation information; real data would be some much more fun!

Can't promise how soon I can get the app on the website as family and Holidays come first!

If you have a file(s) you're willing to contribute, either PM me and I will give you my email address to send it. t Most likely the GPX file will too large for PM.

Thanks in advance, and Best of the Holiday Season to all,

Roy

I've quite a few GPX files recorded by my Tomtom, however they're all weston hemisphere and northern latitude.

They only contain lat-long information, not altitude, a sample I paste below:

I use these to create maps of some of my trips using Google Maps, see here.

You are welcome to more of these if you wish, most, if not all, of the trips referenced I have as GPX files.
I've also written a PHP conversion from GPX to CSV to create the Google forms, and I've got a utility to convert from a Google route to a Tomtom itn format, this is web-based.

Someone beat you to it...

Don't know if it will display the elevation info as I've not often felt a need to do that, and Mapsource seems to do that just fine, also for free.
