wakatools.base.DataFrameAccessor.calculate_residuals#

DataFrameAccessor.calculate_residuals(value: str, raster: DataArray) → ndarray[source]#

Calculate residuals between the values in the DataFrame and the raster values at the DataFrame coordinates. The raster values at the DataFrame coordinates are obtained using TIN interpolation.

Parameters:

  • value (str) – The column name in the DataFrame containing the values to compare against the raster.

  • raster (xr.DataArray) – The raster DataArray to compare against.

Returns:

An array of residuals (raster value - DataFrame value) for each point in the DataFrame.

Return type:

np.ndarray
