1 : 10560 Drawing showing the area around Snodland in Kent. This map is drawn on rectangular sheet lines, enclosed by a black border. Fields are coloured brown where cultivated, and green if untilled. Stonework buildings or structures are drawn in red ink. Those made from less permanent materials, such as wood, appear in black or sepia. Corrections have been made on this plan and it is likely that the altitudes ('spot heights') of individual sites of eminence, noted in red-ink figures, are measured rather than merely estimated or sketched.
1 : 10560 This map, showing the area around Cobham in Kent, is drawn on rectangular sheet lines, enclosed by a black border. Fields are coloured brown where cultivated, and green or blank if untilled. Stonework buildings and structures are drawn in red ink at major settlements. Pencil rays intersecting across the map, discernable beneath the inked detail, are evidence of angular measurements taken by the surveyor between fixed triangulation points. Altitudes on sites of eminence ('spot heights') have been measured and noted in red-ink figures.
1 : 31680 This plan of the North Downs in Kent extends from Addington and Ryarsh, on the left, to Barming Heath, on the bottom right. Rays in red ink intersect across the map, evidence of angular measurements taken by the surveyor between fixed triangulation points. The ruled black sheet lines indicate the edges of the area that will be copied for the finished drawing OSD 120. Pink, George
