A) S = 1, which corresponds to the true map of section in Mariano Melgar, Arequipa, Peru used for simulations. There is no map distortion at this scale. B) Distorted map to a scale of S = 1.5, where the distance between geographic medians of blocks are 1.5 fold the true distance. C) Map distorted to scale S = 2.5, where distance between geographic medians of blocks are 2.5 fold the true distance. Note distance between houses within block is maintained but distance between houses on different blocks is stretched.
