比如tm6个波段,散返打开影像波段组合。basic tools-----statistics----compute statistics----选择打开的影像,确定-----选择convariance,确定,记得到统计袜拿结果,Correlation 这一项为相关系数:
告掘搭 Correlation Band 1 Band 2 Band 3 Band 4 Band 5 Band 6
Band 1 1.000000 0.962418 0.944524 0.722882 0.768651 0.814786
Band 2 0.962418 1.000000 0.968743 0.771633 0.826653 0.864049
Band 3 0.944524 0.968743 1.000000 0.791159 0.865166 0.898138
Band 4 0.722882 0.771633 0.791159 1.000000 0.798735 0.724444
Band 5 0.768651 0.826653 0.865166 0.798735 1.000000 0.953025
Band 6 0.814786 0.864049 0.898138 0.724444 0.953025 1.000000
