2020-09-27 Logging a cycling tour and visualizing the results
We went cycling today and I fixed the speed computer on my bicycle and brought the GPS unit to get a good tracklog. Both worked fine so I know where I cycled, when and how fast. The Garmin GPS saves data in .fit format but it's easy to convert that to gpx using gpsbabel, and visualising the resulting gpx is done with gpxviewer. The maps in gpxviewer are from openstreetmap, which means they are both good and free to use. The magic conversion command from Garmin .fit to .gpx :koos@kernighan:~/garmin$ gpsbabel -i garmin_fit -f 2020-09-27\ 16-37-30.fit -o gpx -F 2020-09-27\ 16-37-30.gpxWhich doesn't produce any output messages when things go well. No news is good news.
