Analyzing user's browsing sequences is an important task of web usage mining. It can help the web administrators or designers improve the web structure or tune the performance of the web servers. Mining on the sequences of such clicking patterns (MSCP) can be considered as a data mining task. MSCP is usually a costly task due to its considerable amount of time for computation and storage for archiving...
Spatial Information Grid (SIG) is a spatial information infrastructure that has the capability of providing services on-demand. It provides a new distributed computing pattern for sharing and operating the massive distributed spatial information resources. The global spatial data directory is an information tree organization used to quickly locate spatial data resources and spatial database nodes...
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...
In the platform of China Geological Survey Information Grid(CGSIG), variety of spatial data of large storage capacity and different data format and spatial services which are various and powerful are collected and put together, therefore it needs a effective mechanism to store, manage, retrieve and discover these geo-resources. Catalogue Service System based on the platform of CGSIG adopts a means...
This paper analyzes the characteristics of geological spatial information sharing at first. In order to break the current ldquoinformation islandrdquo and implement spatial information sharing among virtual organizations, the concept of China geological spatial information grid is proposed. Focusing on the core techniques of grid virtual and collaborative issues, this paper discusses the framework...
In order to solve the two deficiencies in existing massive grid data organization and scheduling: the lack of a universal distributed management method; time-consuming and complex precutting processes, a new strategy is proposed in this paper. It abandons the whole precutting processes in the traditional way. From the view of high efficiency, the new strategy integrates the pre-cutting method and...
