1 : 31680 This drawing is rich in archaeological sites, among them the prehistoric monument known as Stonehenge. Situated on Salisbury Plain, it is the most celebrated megaithic monument in England. The iron-age hillfort of Old Sarum is also marked. A castle and cathedral were built on its earthworks during the 12th century, but abandoned when a new cathedral was built a mile and a half away - the foundation of the modern city of Salisbury. The red line extending from Old Sarum to Beacon Hill is the baseline for the triangulation of the area. Several other archaeological sites are marked: the iron-age hillforts at Vispasians Camp, Ogbury Camp and Clorus's Camp. Crocker, Edmund
This drawing represents the relative relief of the landscape by light shading and interlining in pencil. Parallel pecked lines indicate paths across open land. Achling Ditch, a Roman road, runs diagonally across the drawing. To the left of the road is Blandford Race Ground and Telegraph. As well as being a racecourse until the end of the 19th century, Blandford was used as a military training ground by local volunteers from the 18th century onwards. In 1806, a Royal Navy Shutter Telegraph Station was built near the racecourse. The signal station, on the London to Plymouth route, was closed after the Napoleonic War. In the lower section of the map, concentric rings depict the iron-age hillfort of Badbury Rings.
This is a map of Hampshire by Christopher Saxton, datingfrom 1575. It forms part of an atlas that belonged to William Cecil Lord Burghley, Elizabeth I’s Secretary of State. Burghley used this atlas to illustrate domestic matters. This map is actually a proof copy of one which forms part of Christopher Saxton’s Atlas of England and Wales. This atlas was first published as a whole in 1579. It consists of 35 coloured maps depicting the counties of England and Wales. The atlas is of great significance to British cartography as it set a standard of cartographic representation in Britain and the maps remained the basis for English county mapping, with few exceptions, until after 1750. During the reign of Elizabeth I, map use became more common, with many government matters referring to increasingly accurate maps with consistent scales and symbols, made possible by advances in surveying techniques. Illustrating the increasing use of maps in government matters, Lord Burghley, who had been determined to have England and Wales mapped in detail from the 1550s, selected the cartographer Christopher Saxton to produce a detailed and consistent survey of the country. The financier of the project was Thomas Seckford, Master of Requests at the Court of Elizabeth I, whose arms appear, along with the royal crest, on each map. Lord Burghley added several place names to the map. This map was engraved by Leonardus Terwoort, one of a team of seven English and Flemish engravers employed to produced the copper plates for the atlas.

1 : 21120 Triangulation allows the relative location of individual topographical features to be plotted accurately. This drawing shows the primary triangulation of southern England, the lengths of the sides of each triangle being noted. Stations shown include Dunnose, Bagshot Heath, Inkpen Hill and the Salisbury Plain base. The points of the triangles provided the surveyor with references to which, by measurement or angular observation, he could precisely relate the position of other topographical features. Angular observations were made using a theodolite. Triangulation points were carefully chosen. Elevated sites were preferred where possible, particularly the tops of hills and church towers.
