This session will cover the mechanisms that exist for specifying cross connections between various Wikimedia projects (Commons, Wikidata, Wikipedia) and OpenStreetMap and OpenHistoricalMap. There are connectivity mechanisms in existence that can significantly enhance both projects.
OpenStreetMap for Roman roads? Middle Kingdom cities? 1890s railways? OpenHistoricalMap is aiming to create the most comprehensive, most out-of-date map of everything that’s existed from Then through Now.
