简介:EO-1Hyperion高光谱遥感影像在实际应用中,需对图像进行大气纠正及补偿等预处理,以便获得较好质量的图像。为进一步分析和应用提供保障.笔者运用FLAASH大气校正模型对中国云南香格里拉地区的Hyperion卫星影像进行大气校正,利用图像MNF转换法对光谱曲线进行去噪平滑优化,再对校正前后影像进行遥感影像和典型地物光谱曲线对比分析.结果表明,影像经FLAASH大气校正和MNF平滑后,较好地消除了大气影响和Hyperion高光谱遥感图像的光谱噪声.

简介:全国第二次土地调查于2007年下半年启动,2009年完成,安徽省于2008年4月率先启动了芜湖县的试点工作,并自行购买了ALOS1B1级数据制作DOM,套合上矢量的原始土地利用现状图,以便于外业调绘的全面开展。下面,是笔者对利用ALOS1B1级数据制作正射影像图以及外业调绘用图的方法进行了探讨,研究发现,此方法易于
