@ajft I started tracking the project in 2025; the first post, under "Photo GeoLocation geekiness", is here: https://mastodon.social/@winterknell/113755609082640747
I was already 23% done, so I've completed another 43% in 1.5 years.
I have a database of ~80K photos, with a front end developed across 20 years that lets me import, edit and label my photos. So each 1% done represents ~800 photos. I use Google Maps/Earth and OpenStreetMap to figure out where (give or take) I took each pic.
It's fun. 😺
