On the way to synoptic interpretation of geoscientific data in joint CCS project CO2-MoPa1 Andreas Thomsen,  Sabine Schmidt,  Hans-Jürgen Götzea,  Martin Breunig, Björn Schilberg, Paul-Vincent Kuperb a Institute of Geosciences / Christian-Albrechts-Universität Kiel / Germany {athomsen, sabine, hajo}@geophysik.uni-kiel.de b Institute of Geoinformatics and Remote Sensing / Osnabrück University / Germany {mbreunig, bjoern.schilberg, pkuper}@uni-osnabrueck.de ABSTRACT Within the research framework “Geotechnologien” of the German ministry BMBF and the scientific research organization DFG, the joint project “Modelling and Parameterisation of CO2 Storage in Deep Saliniferous Formations for Dimension and Risk Analyses” (CO2-MoPa) aims at the development and application of an improved model and database system, comprising the hydraulic, geometrical, geochemical, and geomechanical aspects of virtual subterrestrial CO2 sequestration, and permitting dimen-sioning and risk analyses of CO2 storage in deep saline formations. In this context, the task of the subproject CO2-MoPa M3: “Parameter identifica-tion for modelling – validation and Visualization” is the spatial and tem-poral integration of geological, geophysical and geochemical data and their meta-information in a synoptic model within the framework of computer aided simulations of CO2 sequestration.  The heterogeneity of the data to be handled, and the structure of the joint project consisting of ten co-operating work groups situated in different in-stitutions at different locations requires a distributed organization of the information structure that is modular and flexible. Moreover, its use by the different collaborators should not impose much additional work. In partic-ular, different representations of data should not hinder the passage of in-formation.  On the other hand, the management of certain data, in particu-lar spatial 3D models, requires sophisticated special operations.  In order to enhance the navigation between the individual data resources, a meta-information data basis provides information both on technical issues like software and formats, and on scientific content.                                             1 This work is funded within the R&D-Programme GEOTECHNOLOGIEN by the German Ministry of Edu-cation and Research (BMBF) and German Research Foundation (DFG), Grants FKZ03G0686A-D and 03G0645A, as well as by a consortium of private Partners, cf. http://www.co2-mopa.de  The proposed paper briefly addresses some of the challenges of handling heterogeneous distributed geoscientific data, gives an overview on the ar-chitecture of the infomation system under development, and presents the meta-information database and the spatial 3D/4D DBMS DB4GeO (Bär 2007, Breunig et al 2009) for the management of spatial models of the subsurface that provide a geometric basis for further numerical modeling.  The system is based on well-known Web-technology, using the http proto-col in REST (Fielding 2000) style, the XML DBMS eXist (exist 2010) for the management of meta-information on resources, with query language XQuery and XSLT stylesheet transformation between different data for-mats. For the representation of the relationships between information re-sources in a graph structure generated from the resource descriptions, RDF or OWL will be used. Interfaces to relational databases like MySQL and also to MS Access permit to include classical SQL queries. The object-oriented spatio-temporal DBMS DB4GeO written in JAVA uses Apache software for web server functions, and is based on the open source OODBMS DB4O (Db4o 2009). Spatial 3D functions and operations can be invoked via the http protocol, and complex queries encoded in JAVA can be installed on the server side as extensions. Visualization is supported by a “Geo-Wall” installation and software GOCAD (Gocad Research Group 2010), ParaView (Paraview 2010), IGMAS+(Schmidt et al. 2007) permit-ting scientists from different subprojects to observe and discuss large size spatial models, if required in stereo view.
