dctools.data.transforms

Data transformation registry and pipeline utilities.

Functions

build_transform_pipeline(config_list[, ...])	Factory to build a composition of transforms from a config list.
detect_and_normalize_longitude_system(ds[, ...])	Detect the longitude coordinate system and normalize it in the -180° to 180° range.
get_dataset_transform(alias, metadata, ...)	Retrieves the appropriate transformation pipeline for a dataset based on its alias and name.
register_transform(name)	Decorator to register a transform class.

Classes

AssignCoordsTransform(coord_name, ...)	A custom transform dependent on time axis.
CustomTransforms(transform_name, ...)	Wrapper for dataset transformations.
InterpolationTransform(dataset_processor, ...)	Transform to interpolate the dataset to target ranges.
RenameCoordsVarsTransform([...])	A custom transform dependent on time axis.
ResetTimeCoordsTransform()	Transform to reset time coordinates.
SelectVariablesTransform(variables)	Transform to select specific variables from the dataset.
StdLongitudeTransform()	A custom transform dependent on time axis.
StdPercentageTransform(var_names)	Transform percentage variables in the [0, 100] range to [0,1].
