| 摘 要： | 为使洪水演进中计算得到的枯燥的水文数据变得直观形象,进一步丰富洪水演进可视化手段,以离散水深点数据为基础,采用两种空间插值方法,对比了不同插值方法所生成栅格的优劣,选用合适的插值方法创建水深栅格,并通过构建镶嵌数据集实现了洪水的动态演进和可视化,直观形象地模拟了洪水演进的过程,为防洪减灾决策提供技术支持。

| Abstract: | In order to make tedious hydrological data from flood routing calculation more visualization and enrich visualization means. In this study, we based on the discrete water depth data and used two spatial interpolation methods to process the discrete water depth data, then, compared the advantages and disadvantages of different spatial interpolation methods to create raster, finally, we chose the appropriate spatial interpolation method to create depth grid, and achieves dynamic evolution and visualization of flood by building mo-saic dataset.The method can simulate the process of flood routing apparently and vividly, and it can provide technical support to make the right decision for the flood control. |
