There has been a growing demand for knowing time series changes in air dose rate and concentration of radioactive materials. Also, from the beginning of the accident, there were a lot of requests for local monitoring information specialized in the area where individuals live or want to know. To respond to those requests, we had improved and developed the information systems using software platform for environmental monitoring data which developed already. Several visualization information that made time series changes easier to understand were added to the Environmental Monitoring Database. Also, we had developed the Environmental Monitoring Infographics which statistically analyzes a large amount of environmental monitoring data and visualizes the change of air dose rate and concentration of radioactive materials. Moreover, we developed the Mapping Tool that can map and graph local environmental monitoring information.
