I recorded a GPX file using myTrack HD today, and I wanted to overlay it on Google Maps. However, most of the services I’ve seen required you to upload your GPX file and they will process it for you. This is something I feel strongly against doing.
All it requires is 2 files to be downloaded and it runs really well:
To use it, simply download the files onto your desktop (or whichever folder you prefer), then open the gpxviewer.html file in your browser. Put the GPX file into the same folder, then append gpx=<filename> to the URL, so your URL looks like this now:
If points are too close to each other, some points may not be rendered. To overcome this, I modified gpxviewer.html to add the following lines (or modify the existing ones if you wish):
You have to add these calls before AddTrackpointsToMap() or AddWaypointsToMap(). They make the track width slightly smaller, and do not check the minimum delta between each points before it is actually plotted.
My main purpose was simply for visualization of the GPX file. I think street view and scroll wheel support would have been good.
