  Tracking the history of trees in San Francisco

I've been Git scraping the San Francisco version of this for a few years now.

My https://github.com/simonw/sf-tree-history repo now has 444 commits (most recent one was just 4 days ago) tracking every change that's been made to https://data.sfgov.org/City-Infrastructure/Street-Tree-List/... since March 2019.

I haven't yet done anything with this data, but there is so much potential for visualizations and other fun stuff with it. If anyone wants to have a go please be my guest!

I love the idea of syncing git commit history with data change history, like using git for a repo of data. It's actually quite possible if you use pretty printed JSON as a record format (or other simple linear text formats).

I explored more of this "git as DB backend" in some places including: https://github.com/dosyago/sirdb

Also, just as a headsup to any folks, the SF version of this "tree map" (Heh) is at: https://web.archive.org/web/20230328192805/https://bsm.sfdpw... (O site seems to be down)
