Connecting OGC web services and the Grid using Globus Toolkit 4 and OGSA-DAI

Adapting existing distributed infrastructures to the Grid is a major aim of Germany´s D-Grid initiative. As generic compute and data storage resources as well as management services for Virtual Organizations are well established in the D-Grid infrastructure, it is now possible for existing research communities to use these resources to enhance their existing infrastructures or develop new ones that had not been possible without the enormous amount of compute power and storage provided by the Grid. GDI-Grid is one of these communities and adaptation of existing geospatial infrastructures, especially those based upon the Open Geospatial Consortium (OGC) web services, is subject to current research. We present the results of this research and the resulting implementations in this paper. Special focus hereby lies on compute services, data management, and security.
