The invention relates to the technical field of networked geographic information service and provides a multi-user real-time cooperative system in a distributed geographic information environment and a method thereof. The multi-user real-time cooperative system comprises a client, a network, a server and a distributed spatial database. The client, the network, the server and the distributed spatial database are created in a distributed network environment. The client processes the data of the distributed spatial database through the server and the network. The data of the distributed spatial database logically belongs to the same system, however, the data is physically dispersed on a plurality of stations of the network, and each station of the network has autonomous processing capacity and can execute a local application. A computer at each station at least takes part in the execution of an overall application. The multi-user real-time cooperative system in the distributed geographic information environment can accelerate the processing, management and application and the like of the geographic information data to improve to networking, standardization and shared object, and more easily realizes cooperative application of the large-scale mass spatial data.
