通过分析目前常用的方格网法、 断面法、 等高线求积法和三角网格法等库容计算方法, 研究了如何在 Visual studio. net 2010 和 Arc GIS engine SDK10. 0 环境下, 使用 C# 语言实现三维可视化水库库容计算系统的方法, 并设 计了地形数据处理、 视图处理等主要子功能模块。该系统可利用 Arc GIS 提供的接口及其算法优势直接处理原始 地形数据, 快速建立三维地面模型 T IN, 提高了计算效率且避免了传统库容计算过程中产生的精度损失。

Through the analysis of reservoir capacity calculation methods such as grid method, section method, contour cubage method, and triangular mesh method, the use of C# language to realize the 3D visualization of reservoir capacity calculation sys2 tem was investigated under the environment of Visual studio. net 2010 and Arc GIS engine SDK10. 0, and the main sub function modules such as terrain data processing and view processing were discussed. The 3D visualization of reservoir capacity calcula 2 tion system based on Arc GIS can process the raw terrain data using the interface and algorithm advantage of Arc GIS, develop the 3D terrain model TIN rapidly, improve the computational efficiency, and avoid the precision loss in the traditional capacity calculation.
