  3. OpenTopography • As an NSF data facility, OpenTopography (OT, http://www.opentopography.org) provides community access to high-resolution Earth science-oriented, topography data, and related tools and resources. • OT provides several spatial data access functions and geoprocessing applications packaged as Web services across multiple backend servers. • OPAL toolkit (http://opal.nbcr.net) • OPAL is an open-source toolkit developed by the National Biomedical Computation Resource (NBCR) and the SDSC that enables users to wrap scientific applications running on cluster and Grid resources as Web services. • All Web services are built and deployed by leveraging OPAL toolkit. 3

  4. Service Registry • An SOA based pluggable service infrastructure has been prototyped to enable scientists to contribute processing tools and algorithms for operating on OT LIDAR datasets, for use by the larger community. • Service registry is a key piece for enhancing and achieving reuse of services that allows service providers/consumers to organize information about services and allow facilities to publish their services. 4

  5. OGC WPS (Web Process Service) Services • It defines a standardized interface that facilitates the publishing of geospatial processes, and the discovery of and binding to those processes by clients. • TauDEM (Terrain Analysis Using Digital Elevation Models) services for the hydrology science • Adapted as science driver and community service to connect OT and CyberGIS projects. • TauDEM functions are wrapped as OGC WPS Web services. • A single data access service which invokes a set of OT data and application services. • WPS repository can be suitable for the service registry potentially and these service registry can be used for the service integration and composition. 5

  6. Gordon: Computing Facility • Data-intensive applications that involve “very large data-sets or very large input-output requirements”. • A“data-intensive” supercomputer based on SSD flash memory • Asystem designed to accelerate access to massive data bases being generated in all fields of science, engineering, medicine, and social science. • TauDEMservices, including full OT software stack, has been deployed to a dedicated Gordon’s I/O node. 6
