Interoperability – Spatial Interpolation and Automated Mapping

We report on recent developments in the European INTAMAP (Interoperability and Automated Mapping) project on web services for processing radiological data from the EURDEP data base. First, we briefly describe the goals of this project and its relation to other European initiatives and infrastructures for global monitoring of the environment (GMES and INSPIRE). Then we report on the development of UncertML, an XML-based schema for exchanging uncertainty in form of probability distributions. Further, we introduce new Bayesian methods for spatial interpolation in case of non-Gaussian, skewed and heavy-tailed observations: Bayesian transformed-Gaussian kriging and copula-based kriging. Finally, we illustrate the use of these methods for analysing the SIC2004 Joker data and give some conclusions on the potentials of these methods for the generic spatial interpolation of critical environmental variables.
