Subset Harmony Module
subset_harmony.py
Implementation of harmony-service-lib that invokes the Level 2 subsetter.
- exception podaac.subsetter.subset_harmony.L2SSException(original_exception)[source]
L2SS Exception class for custom error messages to see in harmony api calls.
- class podaac.subsetter.subset_harmony.L2SubsetterService(message, catalog=None, config=None)[source]
See https://github.com/nasa/harmony-service-lib-py for documentation and examples.
- __init__(message, catalog=None, config=None)[source]
Constructs the adapter
- Parameters:
message (harmony_service_lib.Message) – The Harmony input which needs acting upon
catalog (pystac.Catalog) – A STAC catalog containing the files on which to act
config (harmony_service_lib.util.Config) – The configuration values for this runtime environment.
- cmd(*args) List[str] [source]
Logs and then runs command.
- Parameters:
run (args Command and args to)
- Return type:
Command output
- prepare_output_dir(output_dir: str) None [source]
Deletes (if present) and recreates the given output_dir, ensuring it exists and is empty
- Parameters:
output_dir (string) – the directory to delete and recreate
- process_item(item: Item, source: Source) Item [source]
Performs variable and bounding box subsetting on the input STAC Item’s data, returning an output STAC item
- Parameters:
item (pystac.Item) – the item that should be subset
source (harmony.message.Source) – the input source defining the variables, if any, to subset from the item
- Returns:
a STAC item describing the output of the subsetter
- Return type:
pystac.Item
- podaac.subsetter.subset_harmony.harmony_to_podaac_bbox(bbox: list) ndarray [source]
Convert Harmony bbox (west, south, east, north) to PO.DAAC bbox ((west, east), (south, north))
- Parameters:
bbox (list) – Harmony bbox
- Returns:
PO.DAAC bbox
- Return type:
np.array
- podaac.subsetter.subset_harmony.main(config: Config | None = None) None [source]
Parse command line arguments and invoke the service to respond to them.
- Parameters:
config (harmony.util.Config)
- Return type:
None
- podaac.subsetter.subset_harmony.podaac_to_harmony_bbox(bbox: ndarray) ndarray | float [source]
Convert PO.DAAC bbox ((west, east), (south, north)) to Harmony bbox (west, south, east, north)
- Parameters:
bbox (np.array) – Podaac bbox
- Returns:
array, int or float – Harmony bbox
TODO - fix this docstring type, type hint, and code to match (code currently returns a list)
