| 摘 要： | 以2015年Landsat8多光谱遥感影像作为基本信息源,在各地物光谱特征差异分析的基础上,采用谱间关系法与阈值法,构建不同水质水体提取模型,并结合实地水质监测数据及污染源数据,对提取结果进行精度评价与分析。结果表明,基于该方法能将一般水体、富营养化水体与其他地物区别开来,可以准确有效地获取不同水质的水体信息。

Extraction of Water Body with Different Water Quality Types Based on Landsat8 Image |
| |
| Abstract: | With the Landsat8 multi-spectral remote sensing image in 2015 as the basic source of information, on the basis of spectral characteris-tic differences analysis, using spectrum correlation and threshold method , extraction model of water body with different water quality types was constructed, and combined with the field monitoring data of water quality and pollution source data , accuracy evaluation and analysis on the ex-traction results was conducted.The results showed that this method can distinguish the general water body , eutrophication water body from other objects, can accurately and efficiently to obtain the information of different water quality . |
