摘要
利用高空间分辨率的Aster遥感影像数据进行冰川的提取,在提取过程中,根据以前的冰川提取的工作方法,结合本次实验数据的具体情况,设定了一套冰川提取的工作流程,经过检查对比,证明本次提取的工作精度是很高的,达到了实验数据的要求,并对冰舌末端的冰碛物的分类进行了研究,能够取得不错的效果。最后对本文的方法进行了总结及展望。
In this paper, we conduct the glacier extraction using the high resolution ASTER remote sensing image data,. During the extraction, we establish a set of operation flow of glacier extraction on the basis of the method used in the past, and according to the concrete conditions of this time's experimental data. It is proved through examination and comparison that the extraction accuracy is high and has reached the requirements of the experimental data. We also conduct the classification research of the glacial debris at the end of the glacier tongue and have achieved good results. Lastly we sum up the method introduced in this paper and analyze the prospects of this method.
