A mapping of Amsterdam incorporating public participation
done by Amsterdam's Waag Society in collaboration with Artist Esther Polak (2002)
"Every inhabitant of Amsterdam has an invisble map of the city in his head. The way he moves about the city and the choices made in this process are determined by this mental map. Amsterdam RealTime attampts to visualize these mental maps through examining the mobile behaviour of the city's users.
During two months (3 Oct to 1 Dec 2002) all of Amsterdam's residents are invited to be equipped with a tracer-unit. This is a portable device developed by Waag Society which is equipped with GPS: Global Positioning System. Using satellite data the tracer calculates its geographical position. Therse tracers' data are sent in realtime to a central point. By visualizing this data against a black background traces, lines, appear. From these lines a (partial) map of Amsterdam constructs itself. This map does not register streets or blocks of houses, but consists of the sheer movements of real people."
