I love showing people how to use online tools to compare historical maps to modern ones. You can map out your ancestor’s address, check out their neighborhoods “then and now,” map their route to work, see if their old home still exists and more.
Well, the online Smithsonian magazine has created an exciting new interface for six American cities. Now you can compare modern satellite imagery with bird’s-eye views of:
- New York in 1836,
- Washington, D.C. in 1851,
- San Francisco in 1859,
- Chicago in 1868,
- Denver in 1879,
- and Los Angeles in 1880.
You’ll see great city layouts before the fire that claimed much of old Chicago, the San Francisco earthquake, the Lincoln memorial and more. The historical map of New York City is the oldest, but the other maps capture each city at a critical point in their growth. For each city you can look at a historical map with a “spyglass” mouse-over of a modern satellite image, or vice-versa, as shown in the New York City map on the right. Each map is accompanied by a fantastic Smithsonian article; the historical maps come from the amazing David Rumsey Map Collection.
