Hachures
An introduction to recording buildings, A guide to good recording practice, published by Historic Environment Scotland on 5 November 2019, defines hachures as: ‘an effective mode of representing relief on a drawn plan. Their purpose is to indicate the direction and steepness of a slope; the thickness, shape and density of the distribution of hachures on a drawing illustrate the general sense of steepness. Applied properly this method can successfully communicate quite specific shapes of terrain, both natural and man-made.’
