To step even further back, the Mannahatta project has a mapping application that shows the viewers what Manhattan looked like prior to 1609. The year 1609 marks the arrival of the first Europeans and the the project seeks to understand what the ecology of New York City was like before it was paved over.

For a literary reminiscence of J.D Salinger, the NY Times has a mapping showing “Trace Holden Caulfield’s perambulations around Manhattan in “The Catcher in the Rye”. Hover your mouse over each point of interest to see the page and narrative relating to that location. (Hat tip: @kjphotography)
