For the cartophile in all of us, nothing beats a good historical atlas.
Comparing then and now, the farms of yesteryear turned into the thoroughfares of today, can command a special attention, and on July 1 the U.S. Geological Survey sought to capture that attention by launching a massive online tool which allows users to layer more than 100 years of maps across the entire United States of America.
Users can layer a single historical map on top of the modern map, or they can layer multiple historical maps.
The tool is searchable by city, and, of course, users can forgo all the layering and appreciate the aesthetics of individual historical maps.
