Playing with Maps one evening led me to find that at one point I had enabled some kind of tracking, and every single day of my movement was graphed in Maps. Where I went and how long I was there was recorded by Google.

I should do something with this data...

There's a neat site where you can turn your location data into a heatmap: https://theopolis.me/location-history-visualizer/

Google's version: https://www.google.com/maps/timeline

I just had a look at the information Google has been keeping on me, and noticed that when I visited the visitor center for Zion National Park earlier this year, there was a photo of my car's license plate was associated with the event. Any ideas what's going on here?

If the photo was taken with an Android device, and uploaded to Google Photos, most likely Google associated your location with the GPS coordinates in the EXIF data of the photo.

I was at Zion a few weeks ago, and did not see any equipment on the road or in the parking lot that was automatically capturing license plate data, if that's what you're asking.

Where did you see the photo exactly? Was it a close-up of your license plate?

Did you take the photo to remember your tag # for parking purposes?

That's what it would have been for me.

I built this once. I have no idea if this still works. All data is processed locally by the way with the html5 file api

I downloaded this data from Google and mapped every GPS location from 2014 using R.

I just came here to point this out. You can see it on the website. I found out that last year on my birthday I was at the cheesecake factory.

Yea you should "delete" that data on your google account.
