How Maps Became Modern

Welcome!
This is a companion site to the book, Mapping the Nation, which explores a tremendously creative era in American cartography.

From maps of disease and the weather to the earliest maps of the national population, this was a period when the very concept of a map was reinvented. By the early twentieth century, maps had become common tools of analysis, communication, and visual representation in an increasingly complex nation.

Today we live in a world that is saturated with maps and graphic knowledge. The maps on this site reveal how this involved a fundamentally new way of thinking.
