During the Dutch Design Week 2017, Het Nieuwe Instituut organized the Embassy of Data, an exhibition about the role of public and private data in the city. For this exhibition, I developed a data panorama that visualizes all smart-city infrastructure in a 400-meter radius around the exhibition space in the city center of Eindhoven [NL] (Eindhoven is the leading Smart City in the Netherlands). The panorama features data from OpenStreetMap, municipal cameras, cell towers, water-level sensors, directional microphones, air quality sensors, motion, traffic and crowd detection, "City Beacons", citizen classification data, and more than 100,000 geolocated public notifications. All data is presented as light sources in a 360-degree panorama in a way that lights up areas of the city that are more heavily monitored than others. By adding the physical sensors that are used in the city to the installation, it becomes a kind of diorama, helping the audience to recognize the sensors in the city and understand their function. The installation aims to translate the hidden abstraction of these technologies into a readable experience for a broad audience, providing a sense of ownership necessary for a nuanced discussion about the future of smart cities.
