Intelligent geospatial Web services

A geospatial Web service is a Modular application designed to enable the discovery, access, and chaining of geospatial information and services across the Web. Earth science applications are often both computing- and data-intensive that involve diverse sources of data and complex processing functions. It is often not only time-consuming but also difficult to find, obtain, and process heterogeneous geospatial information. Web services provide it promising prospect to have most of data discovery and preprocessing work done automatically over the Web. In order to solve real-world geospatial problems through Web services, an "intelligent" mechanism is required to facilitate information discovery and integration over the network and automate the assembly of service chains. In this paper, we propose an intelligent geospatial Web service approach based oil the Geo-Tree concept. This approach Uses sematic-enriched "Geo-Object", a component of "Geo-Tree", to integrate the views of geospatial services and make them understandable and inferable, and adapts geospatial model-driven methods to automate service discovery, invocation and orchestration.
