2 第 2 页 Difficulties of Interoperability Data sources Data Models Supporting Systems Coordinate Systems …… Heterogeneity of Geographic Information brought by inconsistencies of the following aspects:

3 第 3 页 Is it possible to SHARE DATA directly and online instead of downloading, transformation or manually transfer? Is it possible to SHARE processing algorithms directly and online, to get processing results (INFORMATION)? Problem Statement Is it possible to integrate distributed processing algorithms online to form a Geoscience model (KNOWLEDGE), and SHARE this model and the results of this model?

4 第 4 页 Geocomputation software and tools  Moving toward web-based geoprocessing  Service oriented  High performance computing

5 第 5 页 Geospatial Service Web (GSW)

6 第 6 页 Conceptual framework - definition  Geospatial service web is essentially a web service-based virtual platform that integrates geo-spatial resource acquiring, intelligent information processing, and knowledge discovering services, with high performance computing infrastructure and sensor web supported at the back end. Sensor webHPC Resource acquiring services G eospatial S ervice W eb Intelligent processing services Knowledge discovery services

22 第 22 页 Documents, API and Demos GeoSquare is an open platform

23 第 23 页 Technologies in GeoSquare  GeoComputation Portal  Liferay Portal Framework  Java  Registry Center  GXT 、 Java 、 MySQL  Google Map API  GeoChaining  RCP 、 SWT/jFace 、 GEF/EMF/GMF 、 WS-BPEL 、 Servlet  Google Earth API  ActiveBpel Engine  OpenRS parallel framework

24 第 24 页 Geospatial Service Web (GSW) tries to provide a highly intelligent geospatial middleware that integrates various geospatial resources through the Internet based on interoperable Web services technologies. The development of the GSW will focus on the establishment of a platform where data, information, and knowledge can be shared and exchanged in an interoperable manner. Conclusion
