Open Historical Maps: Crowdsourcing, Open Source GIS, and the Research Web

Talk and presentation with Schuyler Erle to the ABCD GIS Seminar Series, Harvard University, 15 April 2009.

Our presentation will show how open source GIS and curated “crowdsourcing” can create an infinite archive of places for digital historians and ethnographers. While the importance of space and place to their research has long been acknowledged by social scientists, there remains a wide gap between their theoretical concerns and the data-driven empiricism of GIS. For those without technical or database skills, maps and geodata are mostly commonly to illustrate rather than advance an argument. However the web can render the tacit knowledge of geography implicit in most historical and ethographic narratives available to the scholars in entirely new forms. We will showcase our ongoing work with the Maps Division of the New York Public Library on a web-based Map Rectifier and Digitizer, a platform for scholars and entusiasts to georeference scanned historical maps and digitize historical features of cities and the environment.
