atNight - Designing the City at Night [atnight.ws] is a research project at Universitat Politècnica de Catalunya led by Mar Santamaria (researcher) in collaboration with Pablo Martínez (lighting designer) and Jordi Bari (engineer). It investigation consists of comparing different representation techniques of the city, more particularly the city of Barcelona, Spain.
The website contains a large series of maps that each reveals a specific 'hidden' structure of the city. The map themselves are based on geolocated information retrieved from various data sources, such as Flickr, Twitter, Instagram, taxi locations and Google Places.
The main visual filter throughout all the maps is the contrasting of day time versus night time, as the ultimate goal of the project focuses on the creation of 'nightscapes', the visualization of the city organization by night.
