I have 5 Landsat images for the same study area. One of them in 1975 (Landsat 2 MSS), two in 1985 and 1995 (Landsat 5 TM) and one in 2005 (Landsat 7 ETM+) and the last one in 2014 (Landsat8 OLI). I want to produce land cover for every time and produce Normalized Vegetation Index (NDVI) and compare the results between for the periods (1975, 1985, 1995, 2005, and 2014). LandsatTM5, Landsat 7 ETM+ and Landsat8 OLI are easily comparable because they have common bands. I am wondering how can I make change detection and deals with Landsat 2 MSS? To be informed the resolution for (Landsat 2 MSS) is 60m and the other sensors their resolution 30m how can I deal with this problem?
