gstools.transform.discrete

gstools.transform.discrete(fld, values, thresholds='arithmetic', field='field', store=True, process=False, keep_mean=True)[source]

Discrete transformation.

After this transformation, the field has only len(values) discrete values.

Parameters:

  • fld (Field) – Field class containing a generated field.

  • values (numpy.ndarray) – The discrete values the field will take

  • thresholds (str or numpy.ndarray, optional) – the thresholds, where the value classes are separated possible values are: * “arithmetic”: the mean of the 2 neighbouring values * “equal”: divide the field into equal parts * an array of explicitly given thresholds Default: “arithmetic”

  • field (str, optional) – Name of field to be transformed. The default is “field”.

  • store (str or bool, optional) – Whether to store field inplace (True/False) or under a given name. The default is True.

  • process (bool, optional) – Whether to process in/out fields with trend, normalizer and mean of given Field instance. The default is False.

  • keep_mean (bool, optional) – Whether to keep the mean of the field if process=True. The default is True.

Returns:

Transformed field.

Return type:

numpy.ndarray
