Abstract	How to manage and utilize huge amounts of spatial data more efficiently is very important for data sharing and applications. This paper presents the research work of a general model of data service in China Spatial Information Grid. This project is to provide a foundational infrastructure for sharing large quantity of earth observation data and earth science applications in grid environment. It is uneconomical to write different middleware for heterogeneous data sources, so how to provide a general model with standard interface becomes important. First we discuss the special problems of data service in SIG. Then we classify currently EO data providing modes into three types. In detail, we show layer design of this general model, and illustrate by query and access services, which are the most frequent operations for data service. Then we describe the implementation of this model, and analysis middleware and standard interface design to support multi-data combination.
