In this fantastic topographic map of the moon, we get to see the
low-points and high-points as they would be colored for any Terran
location, which gives us an impression of what the moon would look like
if it were a green planet, where it's oceans, if there were such things,
would be located, and so also what those coast lines would potentially
look like. In addition to that, the craters add such interest to the
landscape. This map comes from an online astronomy site, http://cseligman.com/text/moons/moonnear.htm, where maps of many other views of our moon are also available.
The above map of Nashville TN shows details of a Cholera outbreak, defining where the illness sprang up and illustrating quite handily the source of the water-born disease. It also shows that the wells and still water were more contaminated, than the moving waters of the river and streams. Maps like this are so incredibly useful- and this is an early example of finding the correlations between geography and public health. This map is from a cholera specific website, http://www.nlm.nih.gov/exhibition/cholera/images.html, and was created in 1873.
