Geographic data multi-database collaborative updating maintenance method and maintenance system

The invention relates to the field of geographic information system application, in particular to a geographic data multi-database collaborative updating maintenance method and maintenance system. According to the geographic data multi-database collaborative updating and maintaining method, a terminal and a server side are included, a map updating preprocessing module is deployed on the terminal, and a plurality of databases and a synchronous service module are deployed on the server side, and the method comprises the steps that 1, the map updating preprocessing module on the terminal preprocesses geographic data, and the preprocessed geographic data obtains a unique identifier; the unique identifier is used for marking the synchronization relationship of the data; 2, a synchronization service module located at a server side sets synchronization marks for tables of different databases, and 3, the synchronization service module receives the geographic data from the map updating preprocessing module and distrib
