British Library Maps – Georeferencing Maps

Are you interested in local history and old maps? Would you like to explore historic places across the globe? If so, you can help the British Library. You can quickly create an overlay of historic maps on current mapping and compare the past with the present.  Online geographic tools allow historic maps to be viewed alongside modern-day mapping, allowing comparison of the past with the present and enhancing findability.  Georeferencing,  i.e. assigning points on a map image to corresponding geographical coordinates, links the historic map to its spatial location on the ground using universal geographic standards (latitude / longitude).
.
To participate, watch the informative video on line and try your hand at helping to make the British Library’s vast collection of maps fully searchable and viewable. All georeferenced maps are added to the portal Old Maps Online, which uses a geographic search interface to identify and view historic maps from numerous collections online.
