Cholera maps appeared in the 1830s as the epidemic spread in Britain. It was the result of the development of British cartography and demography, the establishment of the Register-General and people's interests with "visibility" of disease during this period. In the mid-19th century, cholera maps made by Thomas Shapter, Augustus Petermann, Henry Ackland and John Snow were all products of their time. Examining these cholera maps of this period, all have the same characteristics of spatiality, visibility, and practicality, and were of great significance to medical geography, public health, and subsequent development of mapping. At the same time, cholera maps were often the basis for the alternative miasma theories and had the same limitations of that period.
