ENVI software (V 5.3) has a problem with opening some Metadata files. An error appears which means it does not seem to be a Metadata file. How can I solve this problem?
It depends on satellite data you would like to open..You may kindly go through https://www.l3harrisgeospatial.com/docs/envirastermetadata.html, if efficient in coding. Else you can check/change the extension of you metadata file to an appropriet convention. Hope it will help
