青藏高原MODIS图像冰雪信息挖掘与动态监测分析

Snow Information Extraction and Dynamic Changes Analysis of Tibet Based on MODIS Data

针对西藏地区的环境特点,对适应大区域尺度及全球尺度的MODIS数据进行冰雪信息挖掘与监测的方法进行改进,提出适于西藏地区MODIS数据雪信息提取的技术途径,实践表明,该法对冰雪情监测具有较好的实用性。

Considering the environmental features of Tibet, the method of snow information extraction and snow monitoring which is suitable to the large regional scale and global scale based on MODIS data was improved in this paper and then the method and technical route of snow information extraction which is suitable to Tibet based on MODIS data was put forward. It also analysed the dynamic changes of snow information and identified the existing problems and the solution schemes. The research result indicates that this method is more efficient for snow monitoring.
