Abstract: The application based on distributed structure has the assets of expansibility, configurability, flexibility, reliability and multi-platform etc. In practice, people find that CNGIS essentially requires to be designed as a distributed structure. This paper mainly deals with some design principals and implementation-techniques of the distributed CNGIS. The distributed CNGIS is an efficacious method to share the magnanimity special data and attribute data. With the distributed design, CNGIS solves the problem of user-distributed, especially data-distributed.
