RadianceScape is a data-visualizing audiovisual piece. It based on the live radiation data from the Safecast.org, a global sensor network for collecting and sharing radiation measurements, to generate a cityscape. It appears in point-cloud depth-mapping visuals in which the density of the radiation level represents the visibility of the cityscape. The sequence of the images was grabbed from Google Streetview API’s hidden depth-map data.
In the sound composition it is based on the relative radiation data to generate different tones of drone ambience and noise. The graphic scores were composed using the mapped data-log. It consists of two separate parts, first illustrating the route through Hong Kong, visualizing the radiation levels from Mongkok to the Tsim Sha Tsui area. The second part illustrates the route through Fukushima, visualizing the radiation levels from the Fukushima Prefecture to the nuclear power plant.
