I would like to ask a question. I am doing the research LULC change detection using Landsat 7 etm + image in 2000 and Landsat 8 image in 2014. Both are L1T images. So, do I need to do geometric correction using topographic map for my study area? I have the topographic scanned maps produced in 2002. I would like to have your suggestions. Thank you very much.
