How to Visualize your Google Location History
Raw
LocationHistory.md

Google is extremely transparent about the Location History it has on you. You can check it out on the timeline feature in the Google Maps application on the phone, or on https://www.google.com/maps/timeline It is possible that you have that turned off, and in that case, consider yourself lucky.

If there is data there, you can view it online, or Download and Analyze it yourself.

Note: The conversion script has been updated on 2024-06-24, to match the updated format which is now generated by Google Takeout

Not sure if I am doing this right,.. but I had the same issues with the timeline... need to be able to retrace my travels over the past weeks / months. So I tried something: https://github.com/usbrpa/timeline2map Feel free to have a look.

just logged in to say this worked for me. Had to pull out all my timeline history for a court apeal and this tool did the trick. Thanks

Indeed, https://github.com/usbrpa/timeline2map works pretty nicely. thanks @usbrpa

It uses the export straight from your android device settings, rather than the one exported via google itself

It's easier to ask chatgpt to generate a view that directly reads the json into a map:
