you cannot apply sen2cor to a tif file. Only the original L1C products are supported.
Many thanks! This GeoTIFF file was exported after I processed it from the GEE platform. How can I correct it by atmospheric correction and topographic correction?
Atmospheric correction requires metadata. These are only available in the original product.
There is an orthorectification tool under
Optical > Geometric > Orthorectification, but I’m not sure if it works on single Tiffs.
Actually, most image sets on Google Earth Engine are well geocoded and orthorectified and in some cases also calibrated.
Oh! Thanks a lot, you look so handsome too.
