When attempting to import Landsat-8 data downloaded from the USGS it fails with the error “The given input file is not in the USGS format”. Is it possible to use this data in ERDAS IMAGINE?
The USGS altered the naming format of their *.tar.gz zipped compressed files, using the product ID instead of the scene ID for the filename. This causes a problem with the Landat-8 from USGS importer which expects the filename to use the scene ID.
The solution is to change the name of the *.tar.gz file to match the scene ID. Open the scene’s metadata file and look for the LANDSAT_SCENE_ID number and use this as the filename. For example, the downloaded file “LC08_L1TP_037025_20170325_20170329_01_T1.tar.gz” should be renamed to “LC80370252017084LGN00.tar.gz”.
Another option is to manually extract the TIFF files from the *.tar.gz file using a program like WinRAR or WinZIP. Then display the individual TIFF files as a virtual stack in a 2D View or use the Layer Stack tool to combine the TIFF files for each band into a multi-layer image.
