摘要
利用可见光和近红外波段的地物光谱反射率差异可以从遥感数据中提取水体。利用归一化植被指数(ND-VI)从2个MODIS空间分辨率为250m的遥感数据中提取水体,并进行假彩色合成,实现遥感数据水体制图。
Using the difference of the visible light and near infrared band reflectance, the water bodies can be extracted from remote sensing data. The water bodies which are extracted using the NDV I from MOD IS images have combined to form a new color image. The mapping of water bodies are realized from remote sensing data.
