imod.formats.idf.open_dataset#

imod.formats.idf.open_dataset(globpath, use_cftime=False, pattern=None)[source]#

Open a set of IDFs to a dict of xarray.DataArrays.

Compared to imod.idf.open, this function lets you open multiple parameters at once (for example kh values and starting heads of a model), which will each be a separate entry in a dictionary, with as key the parameter name, and as value the xarray.DataArray.

Parameters:

  • globpath (str or Path) – A glob pattern expansion such as 'model/**/*.idf', which recursively finds all IDF files under the model directory. Note that files with the same name (part before the first underscore) wil be combined into a single xarray.DataArray.

  • use_cftime (bool, optional) –

    Use cftime.DatetimeProlepticGregorian instead of np.datetime64[ns] for the time axis.

    Dates are normally encoded as np.datetime64[ns]; however, if dates fall before 1679 or after 2262, they are automatically encoded as cftime.DatetimeProlepticGregorian objects rather than np.datetime64[ns].

  • pattern (str, regex pattern, optional) – If the filenames do match default naming conventions of {name}_{time}_l{layer}, a custom pattern can be defined here either as a string, or as a compiled regular expression pattern. Please refer to the examples for imod.idf.open.

Returns:

Dictionary of str (parameter name) to xarray.DataArray. All metadata needed for writing the file to IDF or other formats using imod.rasterio are included in the xarray.DataArray.attrs.

Return type:
