Service-Oriented Geographic Information Sharing in Polar Regions

In polar exploration, it is of great importance to unify the geospatial data representation and must be unified seamlessly integrate the output. In this paper, a service pool based geographic data sharing model is proposed, based on the characteristics of polar geospatial data, including multi-source, heterogeneous, and decentralized properties. Furthermore, a service oriented geographic information sharing platform was developed specifically for the polar environment. The proposed platform is based on the standard base map from comprehensive environmental survey and assessment, integrated with novel technologies such as resource pool based controlling, multi-service smooth linking, thematic map rendering services. To validate the developed system, the authors standardize over 130 sheets of polar maps and share the spatial information online in map format using service resource pool based data sharing model. The background GIS server also supports spatial analysis, which make it possible to meet the requirement of multi-dimensional data sharing applications. The system can efficiently achieve data sharing for polar expeditions, providing comprehensive technical support to the data integration, and also offer a solid platform for subsequent data representation and sharing.
