I have been resampling and subsetting a load of S2 imagery to convert them to geotiff to import into ENVI through the batch processing operation. However, my resampled and subset imagery looks markedly different to the 2A product and the pixel values are very different. I was wondering if I have missed a key step somewhere. I pulled together a graph first with read, resample (to 10m using B2 as a reference band) and then subset using a WKT in the geographic coordinates and then write the end product as a geotiff. I then used this graph as the basis for my batch processing. Should I have saved a s beam-dimap and then exported this out as a geotiff?
Any help much appreciated.
