Experimental short by Frederik De Wilde about two guys sneaking into to Fukushima’s post apocalyptic radioactive exclusion zone.

The short combines found footage and computer generated visuals made with custom open source software for artistic data visualisations. Gps data and radiation measurement data collected by Japanese citizens traveling across Japan with an open source Geiger counter and connected gps, was used to create a dynamic data visualisation.

To realise the project we used 22.8M radiation and gps data points collected by citizens using Safecast, a global project working to empower people with data, primarily by mapping radiation levels and building a sensor network, enabling people to both contribute and freely use the data collected. Custom software was created Frederik Vanhoutte in Processing to read the Fukushima Safecast data. Elevation data from Japan was used from Viewfinder Panoramas.
