GPS Track viewer for sports

[fabi1cazenave]

I’d love to have a client-side web app to handle the GPS tracks that my sports watch logs. This should work on a desktop browser, on Firefox for Android, and be available as a FirefoxOS application.

Key Features

• open GPX and TCX tracks
  • display the track on Google Maps or OpenStreetMaps
  • display additional TCX data on a graph:
    • X-axis = distance
    • Y-axis = elevation / heart rate / speed / whatever
• convert GPX+HRM ⇋ TCX
  • build a TCX file from a GPX and an HRM file
  • extract HRM data from a TCX file
• publish to RunKeeper and Strava

Bonus Features

• grab a track on the fly with a GPS-enabled smartphone — have a look at the RunRunRun project for that
• best possible offline usage (e.g. extract a bitmap image of Google Maps / OSM for each GPS track)
• support for other GPS track formats (e.g. KML/KMZ import and export)
• importing Garmin FIT files would be awesome! (FIT files are a compact, binary version of TCX files. Sort of.)

Helpers

There are already a few open-source projects that could help:

• Leaflet + GPX plugin
• Open Layers;
• GPX Viewer;
• GPS Babel and a few Python scripts should give good examples of GPX format converters.

State of the art: My GPS Files is a pretty neat app to view and edit GPX tracks client-side; unfortunately, the source code is not publicly available. The idea of this project would be to have a free, mobile-friendly GPX viewer — not an editor.
