Hello Vera,


Although some remote sensing scientists were not too happy when the USGS adopted cubic convolution, the differences between those derived products and a nearest-neighbors product would be rather minor, particularly now that the radiometric resolution has been increased from 8-bit to 12-bit. I would not suggest seeking out unprocessed Landsat images, even if you could find them. The way that Landsat imagery are being produced today is a tremendous improvement over older systems, even from 10 years ago (notably, of course, that they're free). Only in very particularly circumstances would this be a problem, and for a time series classification, you should have no worries.
