In the distributed architecture of Grid GIS, the key part is to share spatial information resources, these resources include spatial data resources and spatial service resources. This paper will research the spatial service resources sharing in Grid GIS environment, and put forward a strategy of service migration based on WSRF. by this strategy, and combined with the stateful resource of grid service,...
Service migration is important for the execution of distributed spatial tasks because the spatial data published in autonomous Grid node is often not permitted to be freely transferred in Spatial Information Grid. In this paper, we design and implement a scalable service migration framework. In our framework, all spatial services are composed of fine-grained meta-functional components and managed...
This paper discussed the key technologies for building a Geospatial Information Grid service workflow and describes the design and implementation of a Grid GIS service integration and hybrid invocation prototype framework: the MapGIS Grid Workflow Framework (MGWF). First, we discussed the WSRF based GIS function encapsulation details for legacy GIS system. Then we researched on the Grid GIS services...
