A collaborative project by Queen's University Belfast, King’s College London, and the Bodleian Libraries offers an innovative approach that explores the ‘linguistic geographies’ of the Gough Map, the earliest surviving geographically recognizable map of Great Britain.
From the Physorg.com article on the project:
One of key outcomes of Linguistic Geographies is to make available online a searchable version of the Gough Map based upon a digital image of the map. The website features a zoomable, pan-able digital version of the Gough Map - this map is fully searchable and browse-able by place name (current and medieval), and also by geographical features. Once clicking on a chosen location, information regarding that location's geographical appearance, etymology, appearance on earlier maps, and much, much more is revealed.
