Generate multi-resolution levels.
$ xcube level --help
Usage: xcube level [OPTIONS] INPUT Generate multi-resolution levels. Transform the given dataset by INPUT into the levels of a multi-level pyramid with spatial resolution decreasing by a factor of two in both spatial dimensions and write the result to directory OUTPUT. INPUT may be an S3 object storage URL of the form "s3://<bucket>/<path>" or "https://<endpoint>". Options: -o, --output OUTPUT Output path. If omitted, "INPUT.levels" will be used. You can also use S3 object storage URLs of the form "s3://<bucket>/<path>" or "https://<endpoint>" -L, --link Link the INPUT instead of converting it to a level zero dataset. Use with care, as the INPUT's internal spatial chunk sizes may be inappropriate for imaging purposes. -t, --tile-size TILE_SIZE Tile size, given as single integer number or as <tile-width>,<tile-height>. If omitted, the tile size will be derived from the INPUT's internal spatial chunk sizes. If the INPUT is not chunked, tile size will be 512. -n, --num-levels-max NUM_LEVELS_MAX Maximum number of levels to generate. If not given, the number of levels will be derived from spatial dimension and tile sizes. -A, --agg-methods AGG_METHODS Aggregation method(s) to be used for data variables. Either one of "first", "min", "max", "mean", "median", "auto" or list of assignments to individual variables using the notation "<var1>=<method1>,<var2>=<method2>,..." Defaults to "first". -r, --replace Whether to replace an existing dataset at OUTPUT. -a, --anon For S3 inputs or outputs, whether the access is anonymous. By default, credentials are required. -q, --quiet Disable output of log messages to the console entirely. Note, this will also suppress error and warning messages. -v, --verbose Enable output of log messages to the console. Has no effect if --quiet/-q is used. May be given multiple times to control the level of log messages, i.e., -v refers to level INFO, -vv to DETAIL, -vvv to DEBUG, -vvvv to TRACE. If omitted, the log level of the console is WARNING. --help Show this message and exit.
