The accuracy of snow cover information extraction in remote-sensing images dependent on a variety of factors, especially in mountain area with complex terrain. This paper aims at analyzing the accurac...
SNOW COVER AREA CHANGING ANALYSIS OVER TIBETAN PLATEAU WITH MODIS AND ASTER DATA
Changing analysis Snow cover Mapping Tibetan Plateau MODIS ASTER
2016/1/3
The Tibetan Plateau is called "the third pole" of the Earth by its highest altitude. So it is the most sensitive area in the world to hydrological cycle and climatic change. Estimating and mapping the...
