[Clive Swan]

Greetings,

I am trying to select band 1 and then use gdal_merge to merge two tiff
files in an AWS bucket.
Getting odd errors.

gdal_merge.py -o
/vsis3/summer-outputs/3_dataupdated/rcp26-2020-coastal_flood-NA-false.tif
/vsis3/summer-outputs/3_data_ready_for_spectra/coastal-undefended-rcp26-2020.tif

 /vsis3/summer-outputs/5_UK_prod_rasters/coastal-undefended-rcp26-2020.tif
 -of GTiff  -co -b 1  -co CPL_VSIL_USE_TEMP_FILE_FOR_RANDOM_WRITE=YES -co
NUM_THREADS=ALL_CPUS --config AWS_ACCESS_KEY_ID KEY_ID --config
