GIS application method based on distributive memory database

The invention provides a GIS application method based on a distributive memory database. The method comprises the steps of obtaining a node range corresponding to data; loading graphs and attribute data thereof; building indexes of data and nodes; receiving a user request sent from a client side, and analyzing the request; determining target nodes according to a query condition corresponding to the analyzed request and the indexes; calling the target nodes to process the request through a structural interface; using the target nodes to process the request and returning a result; returning theresult to the client side. By means of the GIS application method based on the distributive memory database, services are provided to the outside in a clustering mode, and separation of reading and writing is achieved; meanwhile, the overall strong-consistency business support of the space, the attributes, and the topological structure under a distributive environment is achieved, and high real-time synergism is achieved;
