| 摘 要： | 遥感水文模型的输入和输出数据中含有大量的具有时间和空间序列的图像数据。通过可视化分析,可以找出这些数据中隐含的规律。目前遥感水文时空序列数据可视化分析的各个过程相互分离,分析效率比较低,因此基于IDL(Interactive Data Language,交互式数据语言)进行了遥感水文时空序列数据可视化分析系统的开发,并将其应用于EcoHAT(Ecohydrological Assessment Tools,生态水文评价系统)系统的数据分析。利用IDL强大的图像处理和数据计算能力,实现了遥感水文时空序列数据管理、图像显示和图表绘制等功能,使得海量遥感水文数据得到了更高效的利用。

| Abstract: | There are a lot of hydrological spatio\|temporal series image data in the input and output of remote sensing hydrological model.Visualization makes people discover implicit rules from these data seemingly.The visualization analysis process is separated and has low efficiency at present.Therefore remote sensing spatio-temporal series data visualization analysis system was developed based on IDL(Interactive Data Language) and was applied in the data analysis of EcoHAT(Ecohydrological Assessment Tools) System.Using IDL’s powerful image processing and data calculation capabilities,visualization analysis system can realize such functions:the remote sensing spatio\|temporal series data management,image display and diagramming.Visualization makes more efficient use of the massive remote-sensed hydrological data. |
