Source for the Mastodon bot @[email protected] built by Matt Dray. The repo contains a GitHub Action that executes R code on schedule to:

1. Choose a random spot in a bounding box that encloses Greater London.
2. Query the Mapbox API for a satellite image of that location.
3. Generate an OpenStreetMap URL for that location.
4. Post the image and URL to Mastodon using {rtoot}.

The bot was built originally for Twitter as @londonmapbot using the {rtweet} package. Posts to Twitter stopped in May 2023 due to changes in the API terms of service. You can see an older version of the repo from before the Twitter-related code was removed.

For detail on the original Twitter bot see:
