I am using data for Landsat 2, Landsat 5, Landsat 7 and Landsat 8 for same region for change detection analysis. As Landsat 2 has spatial resolution of 60 meter while all the other data are in 30 meter resolution, is it ok if I resample only 60 meter Landsat 2 data to 30 meter?

    Welcome to GIS.SE. Depending on the background and goal of your work it could be done, or it shouldn't. Why don't you ask a colleague or your supervisor? – Erik Jan 22 at 10:50
