Three-dimensional digital system capable of displaying inundation compensation information of downstream beach area of Yellow River

Abstract

The invention discloses a three-dimensional digital system capable of displaying inundation compensation information of a downstream beach area of a Yellow River, and the system comprises a beach areasocial and economic information management subsystem and a beach area three-dimensional information display subsystem, which are designed according to the architecture of a data layer, a data accesslayer, a system application layer and a system presentation layer. The information of the beach area social and economic information management subsystem is the basis for the beach area three-dimensional display system to perform inundation statistics, and after the beach area three-dimensional information display subsystem calculates the inundation village, inundation loss statistics and three-dimensional scene display are performed according to the village information stored in the social and economic information management database. According to the method, corresponding decision-making activities can be carried out on the information of the downstream beach area of the Yellow River, a comprehensive, dynamic and visual technical means is provided, scientific, rapid and reliable social and economic influence analysis, disaster loss assessment, scheme optimization and other supports are carried out, and the method has important significance in comprehensively improving the scientificity, accuracy and reasonability of decisions.

Description

technical field [0001] The present invention relates to the technical field of flood control and disaster reduction, in particular to a three-dimensional digital system capable of displaying submerged compensation information of the lower reaches of the Yellow River. A 3D digital information system capable of displaying submerged compensation for floodplains in the lower reaches of the Yellow River. Background technique [0002] In recent years, the sedimentation of the main channel of the lower reaches of the Yellow River has shrunk, reducing the width and flow area of ​​the channel, and raising the average elevation of the river bed. Small and medium floods can cause flooding in the floodplain of the Yellow River, floods occur frequently, and the flood control situation is severe. Affected by the flood, the economic development of the downstream beach area was slow, seriously affecting the overall development of the social economy. [0003] At present, the relevant manag...
