Questions about Britain and the world, mapped

Interactive studies of the past, the landscape and the weather, in Britain, across Europe and around the world, built from open data. Search your town, drag a slider, switch a layer. Every study has a write-up on the blog and its data and code on GitHub and Zenodo.
