Rough Roads through the British countrside were worn by horses, carts and carriages, and it was not until the middle of the 17th century that travel routes were formally recorded. In those days a surveyor had to walk, and draw the road - with streams, bridges, forests, hills, and sometimes a large tree or rock, as landmarks for guidance... and he also pushed a surveyor's wheel as he walked - to measure the distance travelled.
Sometimes referred to as strip maps, the routes were shown as if on unrolled vertical strips of paper laid side by side. After they had been drawn, they were then engraved onto copper plates for printing, and at the top of each page was a list of the villages along each road.
In 1675 John Ogilby was the first mapmaker to draw, engrave and publish these road maps, - as Britannia... an Illustration of England and Dominion of Wales - grandly represented with a decoratively embellished cartouche (title piece) at the top, containing the routes shown; and a compass rose on each road for orientation.
In 1719 John Senex corrected and re-engraved Ogilby's maps for publication, slightly smaller and less elaborate, as The Roads through England Delineated, or Ogilby's Survey, Revised, Improved & Reduced to a Size Portable for the Pocket by John Senex, F.R.S. These were more affordable for people to own and four updated editions were published in the first year alone. Regularly updated until 1792, Senex road maps were the most popular. Perhaps their accuracy had something to do with that... 
Many less sophisticated formats were produced over the years, such as the smaller Paterson's Itinerary Road Maps c.1785. Captain Daniel Paterson produced smaller and simpler maps showed the distance along each road between cities, towns and villages, declaring that "The Whole on a Plan entirely new, and far preferable to any Work of the Kind extant".
