Doddington, Kent(002OSD00000027AU00429000)
This outline drawing of the chalk hills of the North Downs in Kent extends from Sittingbourne, at the top of the map, to Lenham Green and Ringlestone, at the bottom. The map is made up from three pieces of paper joined together. Pencil lines radiating from trigonometrical stations cover the map. These show the angular measurements that were made to enable the surveyor to calculate the distances between topographical features. The ink line ruled across the map indicates the edge of the fair (or prototype) drawing.
