Ordnance Survey - Early Digital Cartography, 1970-1972

decorative graphic illustrating this particular set of maps

These maps illustrate some of Ordnance Survey's initial work in automated / digital mapping in the early 1970s. Ordnance Survey acquired its first digitising table in April 1970 and also a digital encoder for fitting the output to a stereoplotting machine. Thereafter progress was rapid, and following trials, in the financial year 1973-74, 92 maps at 1:1,250 and 179 square kilometres of 1:2,500 scale mapping were produced by digital methods.
