Information Services for Grid/Web Service Oriented Architecture (SOA) Based Geospatial Applications

Geographical Information Systems (GIS) presents data-intensive environment for acquiring, processing and sharing geo-data among interested parties. In order to serve geographical information to users in such environment, Service Oriented Architecture (SOA) principles have gained great importance. In SOA-based systems, Information Services support the discovery and handling of these geospatial services. Some options for Information Services … Read more

Implementing Geographical Information System Grid Services to Support Computational Geophysics in a Service-Oriented Environment

We describe the architecture and implementation of the Solid Earth Research Virtual Observatory (SERVO)’s Complexity Computational Environment. We base our design on a globally scalable distributed “cyber-infrastructure,” or Grid, built around a Web Services-based approach consistent with the extended Web Service Interoperability (WS-I+) model. In order to investigate problems in earthquake modeling and forecasting, we … Read more

Developing GIS Visualization Web Services For Geophysical Applications

The Open Geospatial Consortium (OGC) defines a number of standards (both for data models and for online services) that have been widely adopted in the Geographical Information System (GIS) community. In this paper we will describe our group’s efforts to implement GIS services according to OGC standard specifications in accordance with the Web Services approach. … Read more
