Distributed Geographical Model Service Based on WSRF

Numerous geographical models distributed in different geographical locations or cyberspaces lead to difficulties for sophisticated geographical problems solving due to the heterogeneity and decentralization. Grid computer technology provides a new way to solve problems in geographical sharing and service based on geospatial information technology. The method for understanding, describing and representing geographical models and geographical model service based on WSRF are discussed in this paper, and distributed geographical model sharing service framework is proposed. A prototype of distributed heterogeneous geographical models service platform is developed, and some experiments are implemented to examine the proposed methods. The proposed platform can provide a geographical resource sharing environment for geographical problem solving and geographical experimental in cyberspace.
