Export a trip as GPX or CSV

Every trip SpeedLog records can be exported as a GPX file for maps and training apps, or as a CSV file for spreadsheets. Export is part of SpeedLog Pro.

How to export

1. Open the Trips tab and tap the trip you want.
2. Tap the share button at the top right.
3. Choose GPX or CSV, then pick where to send it: Files, Drive, email, or another app.

What is in a GPX file

GPX is the standard file format for GPS tracks. SpeedLog writes one track point per GPS reading, about one per second, each with:

• latitude and longitude, to six decimal places (about 10 cm)
• elevation in metres, when the phone provides it
• the time, in UTC
• the speed in metres per second, in a <speed> extension

Apps and sites that open GPX files include Google Earth, OsmAnd, gpx.studio and Strava (upload it as an activity from the website). Your route then shows up on a real map.

What is in a CSV file

The CSV file has one row per point and these columns:

To convert speed in a spreadsheet: multiply speed_mps by 3.6 for km/h, by 2.237 for mph, or by 1.944 for knots.

Ideas

• Keep a mileage log for work trips: export each trip as CSV and paste the totals into your expense sheet.
• Compare two runs of the same commute and see where the time goes.
• Upload a bike ride to a training app that accepts GPX.
• Back up trips before changing phones; your data never leaves the phone unless you export it.
