Hi Following this topic I have tested this methodology by converting from UTM 29N to a specific local coordinate system (EPSG:3763) (available at PROJ4) gdalwarp -t_srs "EPSG:3763" band_landsat.TIF destination.tif
With that I got a segmentation error, one TIFFReadDirectory a lot of TIFFWriteEncodedStrip and the destination.tif has a different size. Any tips of what migh be wrong?
