Title An approach to encapsulation of grid processing within an OGC Web Processing Service
Contributors
Abstract Increasingly complex environmental problems and the growth in accessible eospatial data in interoperable formats is leading to the investigation of Grid processing as a potential tool for advanced geo-processing within a standards-based environment. The OGC Web Processing Service (WPS) is an open standardised interface for geo-processing, compatible with technologies being adopted by spatial data infrastructures. We investigate the integration of Grid computing capability within a WPS. Our approach is based on the use of the Job Submission Description Language (JSDL) being developed by the Grid community as a standardised description of computational jobs to be executed on heterogeneous Grid platforms. We develop a mechanism to integrate JSDL resource requirement descriptors within a standard WPS request, and show how process execution and status querying may be proxied to a Grid environment through the WPS interface. A proof-of-concept implementation is developed using an atmospheric particle tracing application and the UK National Grid Service.
