OpenHistoricalMap has proven to be a big laboratory. The original concept was very simple in conception, but has unearthed a huge number of considerations. Those considerations have resulted in a lot of experimentation with ways to make historical concepts work within the OpenStreetMap data model. This talk will discuss many of the issues that have come up, and some of the challenges involved in maintaining general OSM compatibility while at the same time dealing with life cycle and uncertainty problems that OSM doesn’t really need to.
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 OpenHistoricalMap is aiming to create the most comprehensive, most out-of-date map of everything that’s existed from Then through Now.
