Cassini Publishing Ltd (Cassini Maps) has released online an enhanced set of extremely detailed national historical maps. The maps are from the first series of Ordnance Survey’s 1:2,500 County Series maps of England and Wales, with the earliest maps dating from 1853.
Cassini’s 1:2,500 historical map series has been digitally enhanced to previously unseen levels of quality and then geo-rectified – a process that allows them to be re-projected and stored in a GIS as a seamless digital map database.
“At 25 inches to the mile, these are, for much of the country, the most detailed maps Ordnance Survey ever produced before the advent of modern mapping methods,” Cassini’s Phil Johnson explains. “They show virtually every man-made feature of the Victorian landscape and offer fascinating insights into our heritage. The detail displayed in the maps is quite remarkable - a reminder of the considerable skills of the Victorian surveyors and cartographers and a vital resource for historians today.”
The maps are available now from Cassini’s website, www.cassinimaps.com
