Abstract: The distributed spatial data registration container is one of the most important spatial data discovery mechanisms in the platform of National Geological Spatial Information Grid(NGSIG). This paper introduces the design idea about the registration container structure, and explains some important characteristics of the registration container. The two important parts of the container, the node container and the portal container, are described in the paper. The data registration container is implemented in the system of NGSIG platform. The application results in the process of spatial data integration show that it works well.

Key words: distributed, spatial data, registration container, data discovery
