VentureBeat: These coders used 13,000 old photos to make a Google Street View map of San Francisco in the 1800s

Two developers, Dan Vanderkam and Raven Keller, had the brilliant idea to take all the old photographs from the San Francisco Historical Photograph Collection and put them on an interactive map. This map functions similarly to Google Street View, except when you zoom in on a particular place, it gives you photos from as far back as 1850.

The project, called OldSF, lets you manipulate a slider to change the range of years (it goes from 1850 all the way up to 2000). Vanderkam and Keller have geocoded about 13,000 images.

Visit the site here, or look below for some of the best photos we saw from the 1800s, marked with their locations in the city. (All photos via San Francisco History Center/San Francisco Public Library.)
