File:Ordnance Survey Drawings - Bishop's Waltham (OSD 82-1).jpg

English: This drawing was completed in 1806. The detail with which it records the road network is greater than in previous maps - testimony to the Ordnance Survey's urgency and military intent. The Roman road from Winchester to Old Sarum is marked running from the top left of the map, with smaller sections of the road shown in the Chilworth area. The origin and terminus of these roads are also noted. A line with a circle at each end leads from the margins of the map to Morstead. This line was used to plot locations and landmarks. Several "Ancient Entrenchments" are marked, notably an iron-age hillfort near Winchester called St. Catherine's Hill. The fort is indicated by concentric rings of dark, cross-hatched strokes ('hachures'). Week Turnpike Gate is marked on the road between Week and Winchester. The recording of a dog kennel above Little Sombourne and bathing houses on the coast between Southampton and Redbridge reveal the meticulousness of the Survey, and perhaps too the interests of the draughtsman..
