ALOS、TM影像在土地利用中的最佳波段组合分析

Analysis on The Best Band Combination of ALOS and TM Images in Land Utilization

利用凉城县2009年7月20日获取的ALOS多光谱数据和2009年7月9日获取的Landsat 5 TM数据,进行影像预处理(大气校正、几何校正、直方图匹配、图像裁剪等),对凉城县ALOS、TM两幅影像土地利用分类中的最佳波段组合进行实验分析。结果显示:ALOS影像的最佳组合波段为432,TM影像的最佳波段组合为145、345、245、147、347与247波段组合,并结合实际应用进一步确定最佳组合波段。

By use of the multispectral data obtained in July 20, 2009 and the Landsat 5 TM data obtained in July 9, 2009 in Liangcheng, through the preprocessing of images （ atmospheric correction, geometric correction, histogram matching, image cutting, and so on）, the best band combination has been analyzed on ALOS and TM images of Liangcheng in land utilization. The results show that the best band combination of ALOS image is 432, the best band combination of TM image is 145, 345, 245, 147, 347 and 247. And the best band combination has been further determined combining with practical application.
