Subspotting by Dominikus Baur & Daniel Goddemeyer

The Subspotting project captured the cell phone reception for the 4 major carriers (AT&T, Verizon, T-Mobile, Sprint) along the 660 miles of the New York City Subway. Subspotting is the first project to create a comprehensive data set of cell phone reception in the NYC underground.
