Open Historical Map : Re-using outdated information
SOTM 2013
Track 1, Friday September 6th 2013, 14:20
Common work with Jeff Meyer, David Evans, Susanna Ånäs, myself and many others.

Presented by David Evans.
Abstract:
The Open Historical Map is billed as "The world's most out of date map". It is a complimentary approach using the Open Street Map tools that focuses on features that have since disappeared, changed shape or purpose. Because of scale and relevancy issues the Open Historical Map uses its own database instance that imports some of the features of Open Street Map. Editing of the map by users is encouraged, though most of the data comes from automated imports from other historical projects that contribute their mapping information. This presentation will review how the Street and Historical maps can be used together and the approaches used to handle problems of time and accuracy in the historical map.
