I tried to open the geotiff with metadata using ENVI software, but I get the message: "unable to read file as the specified type: LANDSAT_GEOTIFF_META". I'm using ENVI 5.1.

My downloaded data is L1 image data.

The MTL.txt structure starts like this:

GROUP = FILE_HEADER

LANDSAT_SCENE_ID = "LC81730682017237LGN00"

SPACECRAFT_ID = "LANDSAT_8"
