This paper explores combining OGC and Grid technologies for geospatial data sharing. OGC and Grid technologies have different focuses: OGC technologies focus more on interface specifications and encodings for the access to geospatial data sources, while Grid technologies focus more on the collaboration and sharing of resources. By combining both, we hope to leverage each other's strengths. In the paper, we first introduce our Grid-enabled architecture which is based on both OGC and Grid technologies, then we discuss how Grid-enabled OGC web services can be integrated with non-Grid-enabled ones, and finally, we report our initial implementation of a case study.
