So far, my results have been mixed when outputting GPX files from my GPS data. But the GPX export feature on this site is working to spec. Next up will be to use some of the incredibly detailed information from Google to generate KML files too. Then I can output the test data I’m getting from my Pi onto Google Maps.
As with the GPX exporter, the KML exporter will use PHP on the server to read from the GPS data in MySQL to generate the XML file.
