The SPL Atlas.

Interactive maps built by lab members — each atlas takes one policy question and lets you explore it spatially. Everything here runs on open data and open-source tools.

The atlas series is member-built: each workshop cohort takes a policy question, gathers the data, and publishes the result here. Want your name on the next one? Join the lab.
