Structure and realization of spatial information grid''''s node based on NWGISS
基于NWGISS的空间信息网格节点结构及实现

The space information grid can integrate a huge volume of multi-source data from multiple data centers, and realize resource sharing and coordinating. The concept structure of space information services node was studied, the composition structure and work mechanism of NWGISS were analyzed, the structure and prototype system of the node based on NWGISS and OGC interface specification were designed. Experimental result indicates the data node can provide space information services effectively.
