Strange Maps: 'Those badges and the fast fading map of Oz constitute some of the more recent examples of a mysterious British tradition of geoglyphy (i.e. producing figures by exposing chalk substratum on hillsides).

Famous examples include the Cerne Abbas Man (a.k.a. the Rude Giant), the Uffington Horse and the Long Man of Wilmington.'
