Abstract
OGC-based Database/Sensor Federation Framework for Fukushima Radiation Monitoring Data

This talk presents about our R&D project to construct a database/sensor federation framework for radiation monitoring data using OGC(Open Geospatial Consortium) standards. This project is a part of a national project which is managed by NRA(National Radiation Agency) and JAEA(Japan Atomic Energy Agency) to build a national radiation database archive related with the Fukushima nuclear plant disaster. Various sensor data is stored and provided with OGC SWE(Sensor Web Enablement) specifications. The data includes semi-real time monitoring posts, moving car surveys and airborne surveys. For monitoring posts, about 4000 stations monitors the radiation data every 10 minutes. Total number of the archived datasets for other monitoring data is over 50. These data can be easily combined with other open data to get useful knowledge. For instance, combining the monitoring data with weather data can find the effect of snow coverage to dose rate reduction. Other example is a collective dose which is obtained by combining radiation data with population statistics provided as a government open data. These federation is based on OGC based protocols such as WMS(Web Map Service), WPS(Web Processing Service). Other OGC specifications such as GeoSPARQL are also used to federate with Linked Open Data. Prototype applications show the advantages of using OGC standard specification for application productivity.
