What's this?

This is a bot that:

• monitors vessels in a defined geographic area, using the AISHub API
• keeps a log of the last seen date of each vessel (keyed by MMSI)
• posts a notification to a Slack channel when it spots a vessel that's never been to that are before, or last visited before a configurable timeout

It's configured to run once every hour using GitHub Actions, and commits its database of vessels back to GitHub, so it needs no additional infrastructure to run.

Dependencies

If you want to deploy your own bot, you'll need:

• An AISHub API key (which is normally only available if you run an AIS receiver and contribute data
• A Slack channel and webhook set up for posting notifications
