This week on WNYC's New Tech City, host Manoush Zomorodi speaks with Steven Romalewski, director of the Mapping Service at the Center for Urban Research at the CUNY Graduate Center, about mapping before and after Sandy.
Plus, a visit to the map room at the New York Public Library. Cartographers there are working with NYPL Labs to put old maps online and make them useable in the digital age thanks to a process known called "map warping."
