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.

File name	Format	Required	Contents/details
*_MTL.txt	Text	Yes	Key file name. Use this file to open the data set.
*.TIF	GeoTIFF	Yes	TIFF image file. Contains imagery information.

Returned data for supported format

Landsat 1-5 MSS data can be opened directly in its raw vendor format or imported into a PCIDSK (*.pix) file using the key file name. For optimal processing, use the PCIDSK format. The data structure, after it is opened by GDB, is as described in the following table.

Data product	Data returned	Details
Landsat 1-5 MSS	4 x [8U] raster channels 1 x [ORB] orbit segment (L1G only) 1 x [TEX] text segment	Green, Red, NIR, IR bands.
