摘要
现利用Erdas软件,以大汶河流域雪野水库近年的TM影像为基础资料,结合图像处理和遥感应用原理进行了水库库区水面体栅格影像的最小距离监督分类提取,提出了基于遥感技术的水库水域面积提取分析方法,结合水文统计观测数据,得到水库水位面积曲线。相比传统的水库面积测量方法,具有快速,精准,效率高的优势,大大简化了测量过程。
Based on the Erdas software and TM remote sensing data of Xueye reservoir in Dawenhen drainage basin, Combined with the RS theory about the raster data process, the author presents the minimum distance extraction of water surface area method based on RS, which joined with the water statistic data, the author creates the water level-water area curve. Compared with the traditional ways, the idea has the characteristic of quick speed and high efficiency and the measurement process simplification. According to the method comparison and analysis.
