| Apr 3, 2017 at 21:13 | comment | added | adamczi | not much help here, but trying to do some classifications between L8, L7 and L5 images I found out some older images may (not neccessarily) be shifted by a range of kilometers. be sure to check that, it is caused by not using GCPs when calibrating older images (link: landsat.usgs.gov/landsat-processing-details). This info may be related - if you check whether your image was originally L1T or L1GT etc, it is possible your Surface Reflectance derived product has same characteristics - from what I know it can't be repaired, they just eg. didn't have some GCPs back then. | |
| Mar 14, 2017 at 21:00 | comment | added | user5858 | I asked the USGS this question and got this response. I'm not really sure what to make of this: "They use different algorithms, yes. That doesn't mean the datasets are completely incompatible. It means you may need to provide additional information in your study." | |
