Members

__init__(**kwargs)

Do not overwrite me

append_file(all_data, data)

Append data

Parameters

• all_data (podpac.UnitsDataArray) – aggregated data

• data (podpac.UnitsDataArray) – new data to append

Raises

NotImplementedError –

check_quality_flags

A boolean (True, False) trait.

property coverage

data_key

A trait for unicode strings.

property lat_key

property lon_key

min_bounds_span

An instance of a Python dict.

One or more traits can be passed to the constructor to validate the keys and/or values of the dict. If you need more detailed validation, you may use a custom validator method.

Changed in version 5.0: Added key_trait for validating dict keys.

Changed in version 5.0: Deprecated ambiguous trait, traits args in favor of value_trait, per_key_traits.

nan_vals = [-9999.0]

product

An enum whose value must be in a given sequence.

property quality_flag_key

read_file(filelike)

Interpret individual SMAP file from EGI zip archive.

Parameters

filelike (filelike) – Reference to file inside EGI zip archive

Returns

Return type
