Approaches to using end-members for sub-pixel snow mapping with MODIS data in Qinghai-Tibet Plateau

In the article, the research of sub-pixel snow mapping was conducted using moderate resolution data of remote sensing for obtaining high-accuracy data of snow cover in Qinghai-Tibet Plateau. But the end-member database is very large in the research, so the amount of calculation is too great if all the end-members will be used in the unmixing of pixel. In light of the characteristics of end-member database, the method of combining use of typical and neighboring end-members was established for the pixel unmixing of MODIS data in Qinghai-Tibet Plateau. Through the method, the percentage data of snow cover have been obtained in the plateau. Based on ASTER data, the validation has been conducted for the unmixing result in the research, which is quite accurate and reliable.
