- 摘要:
- 选取湘阴县为研究区,应用归一化植被指数法(NDVI)、归一化水体指数法(NDWI)、改进的归一化水体指数法(MNDWI)3种方法进行水体提取试验。结果表明:改进的归一化水体指数法(MNDWI)提取水体信息精度最高,总体精度达到98.0%;研究区内水体总面积为346.904 km2。
- Abstract:
- Taking Xiangyin county as sample,the experiment of extract the water information from the ETM satellite image was conducted by three methods,which was the Normalized Difference Vegetation Index (NDVI),the Normalized Difference Water Index (NDWI) and the Modified Normalized Difference Water Index (MNDWI).The results showed that the MNDWI method could accurately extract the water information,and the precision achieved 98%;The total water area of Xiangyin county was 346.904 km2.
