Pastmapper.com Provides Maps of How We Were

by Matt Ball on December 13, 2011

Pastmapper is a new online mapping interface that provides views of the past. Instead of trying to keep up with ever-increasing map updates, this site aims to answer “What was here?” The site is launching with a prototype that presents San Francisco circa 1853 overlayed onto a current Google Maps. The ability to visualize both today and yesterday, provides an answer to some mysteries as well as opening up all new questions about how your city has evolved.

This inaugural version utilized historical maps from the David Rumsey Historical Mapping Collection. The hope is to expand this interface to every city at every time in history, with as much information about how the city evolved as possible.
