Geospatial science involves acquiring, analyzing, and communicating spatial data, and the Open Geospatial Consortium has established Web‑based interoperability standards while Grid technology enables resource sharing across institutions, leading to the concept of a Geospatial Grid. This paper discusses the challenges of applying Globus‑based Grid technology to geospatial disciplines, the need for geospatial Grids, and their defining features. The authors develop and deploy a geospatial Grid by integrating OGC Web‑based interoperability standards with Globus‑based Grid technology. The resulting geospatial Grid enables interoperable, personalized, on‑demand data access and services across large archives, reducing problems in handling large distributed geospatial datasets. © 2008 John Wiley & Sons, Ltd.
Abstract Geospatial science is the science and art of acquiring, archiving, manipulating, analyzing, communicating, modeling with, and utilizing spatially explicit data for understanding physical, chemical, biological, and social systems on the Earth's surface or near the surface. In order to share distributed geospatial resources and facilitate the interoperability, the Open Geospatial Consortium (OGC), an industry–government–academia consortium, has developed a set of widely accepted Web‐based interoperability standards and protocols. Grid is the technology enabling resource sharing and coordinated problem solving in dynamic, multi‐institutional virtual organizations. Geospatial Grid is an extension and application of Grid technology in the geospatial discipline. This paper discusses problems associated with directly using Globus‐based Grid technology in the geospatial disciplines, the needs for geospatial Grids, and the features of geospatial Grids. Then, the paper presents a research project that develops and deploys a geospatial Grid through integrating Web‐based geospatial interoperability standards and technology developed by OGC with Globus‐based Grid technology. The geospatial Grid technology developed by this project makes the interoperable, personalized, on‐demand data access and services a reality at large geospatial data archives. Such a technology can significantly reduce problems associated with archiving, manipulating, analyzing, and utilizing large volumes of geospatial data at distributed locations.
