How to get Data from an Android phone and visualise it with terraink.app and Inkscape
In 2024, Google announced that they would begin storing your Timeline data (i.e. your Location History) locally on your device rather than in the cloud on their systems. The desktop version of the Timeline viewer was also discontinued since the data is now stored on your phone. But you are still able to export your timeline data
How to obtain your Timeline JSON file:
The most reliable way to obtain a compatible JSON file appears to be via your Android device's system settings, as direct export from the Google Maps app's main interface may no longer be available or straightforward:
- Navigate to your Android device's Settings.
- Go to Location.
- Select Location Services (or a similar entry, this may vary slightly by Android version/manufacturer).
- Tap on Google Location History or Timeline.
- Select your Google Account (if you have multiple).
- Look for and click on an option like "Export Timeline Data" or "Download a copy of your data".
- Once completed, you should find a
Timeline.jsonfile (or a similarly named JSON file containing your location history with "semanticSegments") in your device's storage, often in the Downloads folder. This is the file you should try to use with this converter.Alternatively, you can try Google Takeout to download your "Location History" (select JSON format), which might provide a file named `Semantic Location History.json`.

You can now export your track as a KML or GPX file. Converting from KML to GPX ore the other way around can be done with kml2gpx.com
With this GPX file you can now use terraink.app, to visualise your trip on a map.
Once you have finished, you can download the map as a SVG file. Unfortunately, it is not a true vector file, but a file with a lot of bitmap layers. However, this is an improvement on the flat PNG file. I then improved the map to better fit my needs. I changed the text and added new markers with photos.
My custom markers look like this:
Other nice examples of trip maps can be found on e.g. on Etsy (not from me): Example 1 or Example 2
