The key technology of grid service about Geological Spatial Information in city

Introducing grid service into the Geological Spatial Information System (GSIS) can integrate the heterogeneous geological resources, and pack a variety of spatial geological resources into spatial grid service, which can shield the heterogeneity of all kinds of spatial geological resources. It can provide shared interface with this unified software entity of spatial grid information service to integrate geological spatial information of multiple distributed, heterogeneous, related field together, which implemented shared resources, collaboration and parallel computing. It described research status and development trend of grid service of GSIS, and proposed general grid service framework of GSIS, which defined resource layer, basic service layer, field service layer as well as integrated application layer and analyzed six kinds of key technologies involved of grid service of GSIS; The Geological Survey Information Grid System of China was designed and implemented. The results indicated that the grid service framework and the key technologies which proposed in this article is effective and feasible. It provides a sophisticated resource sharing model and professional application service for the spatial geological resource sharing.
