The invention discloses a gridding supervision system for river and lake regions, a data processing method and a database. Through the Internet, the Internet of Things, the mobile communication technology, the big data technology and the like, the river-lake gridding management and service system is constructed, and a set of management means capable of achieving whole-course accurate monitoring and efficient processing is constructed. The system is based on the WebService technology, adopts a service-oriented SOA framework technology, follows OGC open geographic information specifications andnational geographic information public platform related standard specifications, and realizes river and lake resource online management. In the management process, the management of the system serviceprocess is realized by utilizing the logic service layer. The method comprises the steps of data generation, processing, conversion and service logic relation realization. Service functions realizedby the method mainly comprise information acquisition, case input, case processing, case query, case tracking, result display, basic map operation, patrol track management, user management and the like, so that a river and lake management system is optimized, and the working efficiency is improved.
