How to perform PCA analysis for just 4 specific bands using ENVI (mineral exploration purpose)??

Mohammed Jalal Tazi @Mohammed-Jalal-Tazi

31 December 2022 0 6K Report

Dear community, I hope everyone is doing fine, I'am new in the remote sensing field.

My question is how can I perform PCA analysis on ASTER image for just a specific bands (Band 1, 4, 6, 7) not for all 14 bands? because I want to do statistical analysis (Eigen values and eigen vectors..) on just these specific bands

Any information or guidance on this topic will be appreciated

Thank you
