Sarin is a small Ruby command line tool to redefine the GPS-Positions of Sigma Log File (SLF). The GPS-Positions to match the recorded speed and distance in circle around the mean GPS-Position in the log.
This is useful if you have done an indoor training. In this case the speed and distance will be recorded correctly. But the GPS-Positions will be all on one place (or near on place). If you share the log to to Strava there will be shown wrong speeds and distance. Because Strava will recalculate these values from the GPS-Positions. Thus if you redefine the position with this tool you get a nice log on Strava
Original Log: 0.3km
Converted Log: 24km
To install just run this command in your terminal
$ gem install sarin
To redefine the GPS-Positions in a Sigma Log File simple run this command:
$ sarin my-log.slf
This will overwrite the GPS-Positions in your file. If you don't want to overwirte the file you can specify an output file name:
$ sarin -o new-pos.slf my-log.slf
You also can redefine the GPS-Positions in more than one file. Simple specify a list of files. The following command will redefine the GPS-Position of all slf-Files in the current directory.
$ sarin -o new-pos.slf \*.slf
If you don't want to share your real trainings position. You can also specify a custom location and a custom radius of the activity circle. The Position has to in the format latitude,longitude e.g.: 52.514538,13.350111
$ sarin -r 200 -p "52.514538, 13.350111" my-log.slf
The tool is also packed with some nice default locations. Try it out!
$ sarin -c Berlin my-log.slf
