Abstract

Snow disaster is a serious natural disaster in Inner Mongolia Autonomous Region. It results in a great number of livestock deaths and human casualties. Monitoring snow-cover evolution has a significant social and economical meaning for snow disaster forecasting, snow disaster rescuing, as well as the reconstruction of the post-disaster recovery. MODIS sensors have many significant advantages to monitor snow-cover; furthermore, monitoring snow-cover from MODIS data in Inner Mongolia is a blank research area in China. A swath of MODIS L1B 500m resolution data is chosen as a study data. After a series of processing works are performed on MODIS data, obtains a snow-cover map of Inner Mongolia. At last, verifies the accuracy of the snow-cover map by official released data. The validation result shows that the snow-cover map is accurate so that the application of MODIS data to monitor large-scale snow-cover is very effective.
