The
open-source historical mapping group "has been created to explore the creation of an inclusive open-source historical mapping community, with a focus on Early Modern London, Early Modern England and Wales, Ireland and Scotland, and their relations with the wider world."
"We welcome academics and non-academics to contribute to this group, which is hosted on the Humanities Commons platform, and to advance a culture of exchange of data sets, map layers, polygons, georeferenced data and methodologies."
