podpac.interpolators.ScipyPoint¶

class podpac.interpolators.ScipyPoint(**kwargs)[source]¶

Bases: podpac.core.interpolation.interpolator.Interpolator

Scipy Point Interpolation

method¶

Current interpolation method to use in Interpolator (i.e. ‘nearest’). This attribute is set during node evaluation when a new Interpolation class is constructed. See the podpac.data.DataSource interpolation attribute for more information on specifying the interpolator method.

Type: str

methods_supported¶

List of methods supported by the interpolator. This attribute should be defined by the implementing Interpolator. See podpac.data.INTERPOLATION_METHODS for list of available method strings.

Type: list

dims_supported¶

List of unstacked dimensions supported by the interpolator. This attribute should be defined by the implementing Interpolator. Used by private convience method _filter_udims_supported().

Type: list

Methods

`__init__`(**kwargs)
`can_interpolate`(udims, source_coordinates, …)	Evaluate if this interpolation method can handle the requested coordinates and source_coordinates.
`can_select`(udims, source_coordinates, …)	Evaluate if interpolator can downselect the source coordinates from the requested coordinates for the unstacked dims supplied.
`init`()	Overwrite this method if a Interpolator needs to do any additional initialization after the standard initialization.
`interpolate`(udims, source_coordinates, …)	Interpolate data from requested coordinates to source coordinates.
`select_coordinates`(udims, …[, index_type])	Downselect coordinates with interpolator method
`trait_defaults`(names, *metadata)	Return a trait’s default value or a dictionary of them
`trait_has_value`(name)	Returns True if the specified trait has a value.
`trait_values`(**metadata)	A `dict` of trait names and their values.

Attributes

`definition`	Interpolator definition
`dims_supported`
`method`	A trait for unicode strings.
`methods_supported`
`name`	Interpolator definition
`spatial_tolerance`	A float trait.
`time_tolerance`	A trait type representing a Union type.

Members

__init__(**kwargs)¶

can_interpolate(udims, source_coordinates, eval_coordinates)[source]¶

Evaluate if this interpolation method can handle the requested coordinates and source_coordinates. If not overwritten, this method returns an empty tuple (tuple())

Parameters

udims (tuple) – dimensions to interpolate
source_coordinates (podpac.Coordinates) – Description
eval_coordinates (podpac.Coordinates) – Description

Returns

Returns a tuple of dimensions that can be interpolated with this interpolator If no dimensions can be interpolated, method should return an emtpy tuple

Return type

tuple

dims_supported = ['lat', 'lon']

interpolate(udims, source_coordinates, source_data, eval_coordinates, output_data)[source]¶

Interpolate data from requested coordinates to source coordinates.

Parameters

udims (tuple) – dimensions to interpolate
source_coordinates (podpac.Coordinates) – Description
source_data (podpac.core.units.UnitsDataArray) – Description
eval_coordinates (podpac.Coordinates) – Description
output_data (podpac.core.units.UnitsDataArray) – Description

Raises

NotImplementedError –

Returns

returns the updated output of interpolated data

Return type

podpac.core.units.UnitDataArray

method: A trait for unicode strings.

methods_supported = ['nearest']

spatial_tolerance¶: A float trait.

time_tolerance¶: A trait type representing a Union type.
