| 摘 要： | 通过对混合光谱分解模型的研究,实现了基于IDL的线形混合光谱分解模型的开发,开发过程中实现了遥感数据的读取、混合像元的分解,最终得到了植被组分丰度、水体组分丰度和裸沙组分丰度解算结果的栅格数据。通过程序改写文件格式,成功将该数据接入到地理信息系统中,提取裸沙组分的丰度图,得到裸沙占地百分比专题数据,该数据为荒漠化评价的重要指标之一。

| Abstract: | The development of linear spectral unmixing model based on IDL was realized through the study of spectral unmixing model,including data retrieval and mixed pixel unmixing.Thereby,the raster data of the algorithm result from vegetation endmember,water body endmember and bare sandy endmember were obtained.And the raster data could be successfully linked with GIS applications by modifying file format with programs.Finally,the thematic data of occupation ratio of bare sandy land were got,which is one of the important factors in desertification evaluation. |
