波谱分辨率 meaning in Chinese

spectral resolution

Because of modis predominant space and spectral differentiate rate , it ’ s has been broadly applied to various field , in the aspect of snow monitoring , modis has been successfully using a normalized difference snow index ( ndsi ) to provide global automated binary maps of snow cover . the ndsi is a spectral ratio that takes advantage of the spectral difference of snow in short - wave infrared and visible spectral bands , although it has higher precision , it can only discern one pixel to snow or other features , can not satisfy accurate drainage basin snow cover mapping and snow parameter extracting
Modis数据因其优越的空间分辨率、波谱分辨率,已被广泛的运用于各个领域,在积雪监测方面,已成功地运用归一化差分雪盖指数( ndsi )制作每天的全球雪盖分布图, ndsi是基于雪对可见光与近红外波段的反射特性和反射差相对大小的一种测量方法,然而它只能将一个像元辨别为积雪或非积雪,满足不了高精度应用要求。
