AI Technical Summary

Technical Problem

Existing topographic survey and assessment systems for water conservancy projects rely on only a single data source, making it difficult to accurately reflect the true topographic conditions. This leads to deviations in project site selection, design, and construction, increasing risks and costs.

Method used

A topographic survey and assessment system for water conservancy projects based on multi-source data information is adopted, including a topographic survey center, a data acquisition module, a data processing module, a model building module, and a water conservancy assessment module. By acquiring topographic and hydrological data, a regional planar elevation map is constructed, topographic and hydrological vector features are generated, the correlation between the two is assessed, and key water conservancy nodes are marked.

Benefits of technology

It enables comprehensive analysis of topographic and hydrological data within the target area, accurately assesses the risks of water-land inter-regional areas, provides reference for water conservancy projects, and reduces project risks and costs.

Abstract

The application discloses a water conservancy project topographic survey evaluation system based on multi-source data information, relates to the technical field of water conservancy exploration, and comprises a topographic survey center, wherein the topographic survey center is connected with a data acquisition module, a data processing module, a model construction module and a water conservancy evaluation module. The topographic vector features and the hydrological vector features are obtained by analyzing the topographic data and the hydrological data in the target region. The common region where the topographic vector features and the hydrological vector features are located is analyzed, the mutual correlation between the hydrological data and the topographic data in the common region is judged, the common region with correlation is subjected to specific data analysis, the risk of the common region is judged, the water conservancy key points are marked according to the risk judgment result, and corresponding reference is provided for subsequent water conservancy projects.
