The indication of land relief and attention to communication routes on this plan conform to the military and cartographic standards employed by the West Country survey. The south of England was the area most vulnerable to invasion, especially during the Napoleonic conflicts between 1793 and 1815. Accurate mapping of the Devonshire coastline was, therefore, of great military significance. Towards the left of the plan, the sand dunes of Braunton Burrows stretch southwards from the sea at Barnstaple Bay towards Appledore and Bideford.
South Molton, Devon
This relief on this drawing,is indicated by dense interlining ('hachures'), with,the summits of hills left blank. The drawing has been made on three pieces of paper mounted as one sheet., Dirty, worn and creased, the manuscript is difficult to decipher. ,A pencil note at the base of the drawing reads "To survey from * to * as ...by...the Farms as named."
Topography and areas of natural shelter were both of great importance in planning,any military campaign., To this end, inclines and woodland are clearly indicated on this drawing., The main communication routes are highlighted in yellow., Some roads have been pin-marked along their lengths, proof that the draughtsman used measuring dividers to plot the exact course of the roads., The dates of draughting and the scale of the drawing have been recorded in pencil on the bottom right of the sheet.
