Resumen
It is important to detect and monitor the development of radioactive releases in the atmosphere. In many European countries monitoring networks have been established to perform this task. In the Netherlands the National Radioactivity Monitoring network (NRM) was installed. Currently point maps are used to analyse the data from the NRM. Automatically generating maps in real-time would improve the interpretation of the data by giving the user a clear overview of the present radiological situation. In this paper we present a prototype system that automatically generates real-time maps of the NRM and presents the results in an interoperable way through a Web Map Service. The automatic interpolation is done using universal kriging in combination with an automatic variogram fitting procedure. The focus of the discussion is on mathematical and operational issues and architectural considerations on how to improve the interoperability and portability of this prototype system.
