OpenHistoricalMap is creating a map of everything that has ever existed with a time slider to view how the world has changed over time. It currently has maps from prehistory through ancient and modern history and aims to map yesterday as well. OpenHistoricalMap wants contributors to help add more historical data and take part in a hackday event.
