CPL_VSIL_USE_TEMP_FILE_FOR_RANDOM_WRITE is a configuration option / environment variable, so you have to pass it with --config CPL_VSIL_USE_TEMP_FILE_FOR_RANDOM_WRITE YES Now I am getting a memory issue?? << The input files are 6.9 GB + 672 MB The output should be 7.xx GB 6.9 GB + 672MB numpy.core._exceptions._ArrayMemoryError: Unable to allocate 377. GiB for an array with shape (225000, 450000) and data type float32 Any suggestions appreciated Kind regards, Clive -- Regards, Clive Swan --
