研究基于MODIS(中分辨率成像光谱仪)数据和降水信息,结合地面实测数据进行区域的旱情监测。搭建了基于网格技术的MODIS数据处理平台,对遥感数据进行前期加工,利用水文气象信息,通过分析和选取合适的干旱因子构建遥感干旱综合监测模型。建立了干旱综合监测数据处理系统,初步实现了MODIS数据自动处理和旱情分析的过程。
This thesis focuses on regional drought monitoring by integrating ground measured data with MODIS data and precipitation information. By employing grid computing technology, MODIS data processing platform is established for preprocessing remote sensing data. Comprehensive drought monitoring model by remote sensing is constructed by analyzing and selecting appropriate drought factor according to hydrometeorological information. Thus, comprehensive drought monitoring data processing system is set up for realizing primary automatic MODIS data processing and drought analysis.
