Abstract

The invention provides a drainage network encoding method and system. The method comprises the steps of receiving a drainage network encoding request, obtaining drainage network information according to the drainage network encoding request, obtaining a drainage network information encoding mode corresponding to the drainage network information, encoding the drainage network information according to the drainage network information encoding mode corresponding to the drainage network information, recording drainage network information codes according to a certain sequence to obtain a complete code which is the drainage network code, and searching for the drainage network information and / or obtaining drainage network spatial topological attributes and / or inquiring drainage network auxiliary information according to the drainage network code. The drainage network encoding method and system can solve the problem that drainage network codes are not uniform within the global range, and promote sharing of global drainage network information and development of the global water management informationization process.

Description

technical field [0001] The present application relates to the field of encoding technology, in particular to a river network encoding method and system. Background technique [0002] River network coding can solve the spatial topological relationship, hydrological characteristics and related attributes of the river network system, which is conducive to information sharing and helps to improve the level of comprehensive management of water resources and water environment. An important part of. However, when the spatial scope of the river network expands to the whole country or even the whole world, the river network structure becomes extremely complex, especially in areas with dense river network structure, the river network structure is more complex, so when encoding the river network, it is necessary to target According to the complexity of the river network, a corresponding encoding scheme is proposed, and then the encoding of the river network is automatically realized b...
