I am working on a project, at ArcMap 10.5.1, with Level 1 temporal datasets from Landsat 5, 7 and 8. My target is to calculate the various indices and compare their results over time.
Do I need to perform image to image registration as part of the pre-processing steps or not, because I am using only Landsats? As the Landsat Level 1 collections are consistently georegistered but the image-to-image tolerances is ≦ 12-meter radial root mean square error (RMSE), do I still have to do image to image registration (https://www.usgs.gov/land-resources/nli/landsat/landsat-collection-1?qt-science_support_page_related_con=1#qt-science_support_page_related_con)?
I am confused and I am not sure. How I could check the datasets in ArcMap, if I need to process image to image registration for my research?
