static Datacube.load_data(sources, geobox, measurements, resampling=None, fuse_func=None, dask_chunks=None, skip_broken_datasets=False, progress_cbk=None, extra_dims=None, patch_url=None, driver=None, **extra)[source]#

Load data from group_datasets() into an xarray.Dataset.

Parameters:

sources (xarray.DataArray) – DataArray holding a list of datacube.model.Dataset, grouped along the time dimension
geobox (GeoBox) – A GeoBox defining the output spatial projection and resolution
measurements (Mapping[str, Measurement] | list[Measurement]) – list of Measurement objects
resampling (str|dict) –
The resampling method to use if re-projection is required. This could be a string or a dictionary mapping band name to resampling mode. When using a dict use '*' to indicate “apply to all other bands”, for example {'*': 'cubic', 'fmask': 'nearest'} would use cubic for all bands except fmask for which nearest will be used.

Valid values are: 'nearest', 'cubic', 'bilinear', 'cubic_spline', 'lanczos', 'average', 'mode', 'gauss', 'max', 'min', 'med', 'q1', 'q3'

Default is to use nearest for all bands.
fuse_func (Callable[[ndarray, ndarray], Any] | Mapping[str, Callable[[ndarray, ndarray], Any] | None] | None) – function to merge successive arrays as an output. Can be a dictionary just like resampling.
dask_chunks (dict) –
If provided, the data will be loaded on demand using dask.array.Array. Should be a dictionary specifying the chunking size for each output dimension. Unspecified dimensions will be auto-guessed, currently this means use chunk size of 1 for non-spatial dimensions and use whole dimension (no chunking unless specified) for spatial dimensions.

See the documentation on using xarray with dask for more information.
skip_broken_datasets (bool) – do not include broken datasets in the result.
progress_cbk (Callable[[int, int], Any] | None) – Int, Int -> None if supplied will be called for every file read with files_processed_so_far, total_files. This is only applicable to non-lazy loads, ignored when using dask.
extra_dims (ExtraDimensions) – A ExtraDimensions describing any additional dimensions on top of (t, y, x)
patch_url (Callable[[str], str],) – if supplied, will be used to patch/sign the url(s), as required to access some commercial archives.
driver (Any | None) – Optional. If provided, use the specified driver to load the data.

Return type:

xarray.Dataset
