wakatools.interpolation.rbf

wakatools.interpolation.rbf(*data: DataFrame | GeoDataFrame, value: str, target_grid: DataArray, **kwargs) → DataArray

Interpolate values from a Pandas DataFrame containing x,y,value for a set of points onto a target grid using Radial Basis Function (RBF) interpolation.

Parameters:

• data (pd.DataFrame | gpd.GeoDataFrame) – One or more DataFrame or GeoDataFrame instances containing ‘x’, ‘y’, and ‘value’ columns representing the points to interpolate from.

• value (str) – The name of the column in data that contains the values to interpolate.

• target_grid (xr.DataArray) – Target grid as an xarray DataArray on which to interpolate the values.

• **kwargs – Additional keyword arguments to pass to scipy.interpolate.RBFInterpolator, such as kernel, epsilon, etc. See SciPy documentation for more details.

Returns:

Interpolated values on the target grid as an xarray DataArray.

Return type:

xr.DataArray
