| 摘 要： | 针对利用多源遥感数据进行积雪覆盖监测的需要,在分析不同深度与面积的积雪实测光谱基础上,探讨了在利用NDSI方法进行积雪覆盖遥感监测时,不同积雪深度对其的影响,并以HJ-1B卫星以及MODIS卫星为例,研究了不同积雪面积对遥感积雪反演的影响。结果表明,积雪深度几乎对遥感积雪覆盖监测的结果没有影响,而在积雪面积方面,受所使用的遥感影像空间分辨率的制约,对遥感积雪监测的结果有一定影响。

| Abstract: | For the needs of snow cover monitoring using multi-source remote sensing data,in the present article,based on thespectrum analysis of different depth and area of snow,the effect of snow depth on the results of snow cover retrieval using nor-malized difference snow index(NDSI)is discussed.Meanwhile,taking the HJ-1Band MODIS remote sensing data as an exam-ple,the snow area effect on the snow cover monitoring is also studied.The results show that:the difference of snow depth doesnot contribute to the retrieval... |
