Visualization system for immediately publishing detailed time variation data on the distribution of radioactive substances in Fukushima district is presented. The system visualizes and provides continuous and consecutive air dose rate data measured by devices mounted on buses. It automatically generates scripts for both displaying intuitive distribution data with the help of networked GIS systems and providing graphs on the time variation data in cooperation with web-services. In this presentation, we introduce an outline of the Fukushima air dose measurement project in which the system is utilized, and report elemental technologies for the development of the system.
