Distribution disk files

A Landsat 1-5 MSS data set is organized in a specific folder structure on disk. GDB uses this folder structure and the file names to identify the data product type.

Warning: Data sets for this sensor are organized in a specific folder structure on disk. GDB uses this structure and the file names to identify the data product type. Do not alter the folder structure or any file names prior to data ingestion to ensure the image data and auxiliary information are imported correctly.

In CATALYST Professional programs, such as Focus, you can open a Landsat 1-5 MSS data set in the File Selector window by selecting the *_MTL.txt file.

When opening a Landsat 1-5 MSS data set, the files read by GDB are as described in the following table.
