The New York Public Library is looking for help properly geotagging old images in their archives to find the city's lost history

New York City is ever-evolving and constantly in a state of flux. This means that, over time, entire streets, buildings, and subways lines have disappeared with little to no record of their existence.

The New York Public Library is hoping to re-surface some of that history with their latest project that utilizes a new tool called Surveyor. It asks visitors to look at vaguely-titled old images and help to place them on a map of the city. Once several people have geotagged an image, the tool’s creator Bert Spaan looks to see if there is a consensus, and if so, tags the image. The crowdsourced tool is part of the library’s NYC Space/Time Directory project, which launched in 2015, designed to make the city’s history more accessible.
