| 摘 要： | 在可见光和近红外波段内,水体、植被、城市和土壤等地物的光谱反射率差异是利用遥感手段提取水体的基本原理。利用归一化植被指数(NDVI)提取MOD IS遥感影像上的水体,再将提取出的水体和MOD IS的空间分辨率为250m的2个波段进行假彩色合成,实现湖泊水体遥感影像的自动制图。结果表明,利用本文方法制成的水体分布图,既能保留MOD IS的较高分辨率,又能清晰地识别水体。 |
| 关 键 词： | 中分辨成像光谱仪 归一化植被指数 水体提取 快速识别 |

| Abstract: | 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 images of band 1,2 and the water bodies which are extracted using the NDVI from MODIS images have combined to form a new color image.This color image holds image resolution and makes us quickly recognize the water. |
| Keywords: | MODIS NDVI water extraction quick recognition |
