Abstract:
The snow disaster is the most serious natural disaster for local animal husbandry in northern and southern border areas of Xizang. Using satellite remote sensing data to develop snow monitoring system and provide monitoring information has a practical significance. A method of snow monitoring based on the Tibet Plateau snow identification model using the MODIS data from Lhasa station is described. The result shows that it is feasible to develop the snow identification model through combining MODIS NDSI and NDVI with the data of channels 1, 2, 4, 6; and the model is useful for snow disaster monitoring in Tibet Plateau and can improve the accuracy of the model through considering the differences in land cover between forest and the nonforest areas in the eastern and southern Tibet Plateau especially.
