【Abstract】 Using GIS technology, the authors have designed and realized the management and query system for the road planning in Beijing, solved existing problems and hence gained economic profits. Realizing the synchronous editing of graphic data and attribute data, the system maintains consistency between graphic data and attribute data for road planning. Solving the problem of parallel operation in the case of synchronous querying and editing, the system is run in a safe environment. The system can send out graphic information and attribute information for intersections of discontinuous roads, and the production output is very convenient.更多还原
