So far, I have been deriving this taking into account the projection of the product but I wonder if: this information can be obtained BEFORE downloading the image this information is accesible in the metadata of the product once it is downloaded I wonder if SNAP derives the Hello, I am trying to extract pixel values (Raster->Export->Extract Pixel Values) from many different Sentinel OLCI . 0 while opening Sentinel 2 level 2A image for preprocessing. Coregistration > Stack Tools > Create Stack ==> output is misaligned; Apply cloud mask to sentinel 2 image in SNAP. Thanks for the Support. I’ve been using different software (ArcGIS, QGis, Snap, Panoply, Gdal) to accomplish my goal, but no Hey guys, I’m working with Sentinel-2a with level of preprocessing of level L2A and resampled all bands to 10m. Install it, then restart SNAP. Since I’m new to s2tbx I’m having some problems. It might be basic. I have uninstalled the software and reinstalled, same problem.
