Si quiere estar seguro de que la imagen recortada coincide correctamente con la original ahora y en el futuro, utilice la opción "GEOKEYS para utilizar valores personalizados de claves GeoTIFF". O si encuentra que la diferencia en la georreferenciación es pequeña, puede considerar actualizar el CRS de la imagen original con gdal_edit https://gdal.org/programs/gdal_edit.html -a_srs epsg:3035
