The Subspotting project captures, maps, and visualizes the available cell phone reception along all 21 lines, 469 stations, and 660 miles of track of the New York City Subway.
It is the first project of its kind to capture the cell phone reception in the entire subway system to provide New Yorkers—through a poster and an iPhone app—with information on where to make the next call or send the next text while underground.
