Landsat MSS has two NIR bands (700-800 nm and 800-1000 nm), while TM has a 760–900 nm channel. Landsat 4-9 follow the same spectral bands and are comparable. More information can be found here Article Normalized Difference Vegetation Index Continuity of the Lan...

Chukwuma John Okolie

Rawaz Rostam Landsat MSS has fewer spectral bands, and lower spatial resolution, and this could limit its applications today.

Rawaz Rostam

Chukwuma John Okolie Yes, you are right, it makes sense. I appreciate your comment.
