Georeferencing maps online - will it work?
We're asking the online public to undertake a task beyond our own means: to georeference some of our treasures of British mapping. http://maps.bl.uk
The maps included represent a very small sample, to be sure. But the the Ordnance Survey Drawings are some of the most enquired-after maps we have, being unique manuscript documents that portray the lanscape of England and Wales before the onslaught of industrialisation made its mark.
This is a detail of OSD 40, pt. 3. In 1801, Exeter was a small and compact town!
The other collection we've included in this effort is a selection of the Crace Collection of Maps of London. I've found these maps to be more difficult to georeference, and am eager to see how others fare with them.
The project web page is http://maps.bl.uk - there is a short video there and detailed instructions. Access is also available from within the map pages in the Online Gallery. Please try this new tool out, as it will be a great help towards improving access to and visibility of these collections!
