| 摘 要： | 水是地球上万物的命脉所在,水体提取对于水资源调查、洪水灾害预测评估和环境监测等有着重要作用。而可见光和近红外波段水体与植被、城市和土壤光谱反射率的差异是利用遥感手段提取水体的基本原理。本文利用谱间关系法进行MOD IS图像的水体提取。结果表明,用于提取水体的谱间关系法比归一化植被指数(NDVI)法快速,但谱间关系法有把云错误地当作水体提取的缺点。 |
| 关 键 词： | MODIS 水体提取 谱间关系法 归一化植被指数 |

| Abstract: | Water is the base of living things on Earth.Water extraction is important to the water resources investigation,the forecasting and evaluating of flood disaster and environmental monitoring.The difference of the visible light and near infrared band reflectance among water,vegetation,urban and soil is the foundation of extracting water by means of the remote sensing data.The methods of the relationships among the bands are used in extracting water from MODIS images.The result shows that the spectrum-photometric method extracts the water body more quickly than the method of NDVI,but wrongly recognizes some clouds as water. |
| Keywords: | MODIS water extraction spectrum-photometric method NDVI |
