Figure 5From: Topographic determinants of foot and mouth disease transmission in the UK 2001 epidemicTrue road distances between farmhouses and their entrances onto a road, taken from Ordnance Survey 1:50000 raster images, against the Euclidean distances between the farmhouses and their nearest nodes in our road network (circles). Linear regression through data with Euclidean distance to nearest node greater than 200 m gives y = -60 + 1.03x.Back to article page
