environmentaltools.spatiotemporal.bme.create_spatiotemporal_matrix(dfh, dfs)

Create spatiotemporal data matrix.

Organizes hard and soft data into a matrix format where columns represent unique spatial locations and rows represent time points.

Parameters:

• dfh (pd.DataFrame) – Hard data with columns [‘x’, ‘y’, ‘t’, ‘h’].

• dfs (pd.DataFrame) – Soft data with columns [‘x’, ‘y’, ‘t’, ‘h’].

Returns:

• dfz (pd.DataFrame) – Matrix of values where index is time and columns are spatial locations.

• coups (np.ndarray) – Array of unique spatial coordinate pairs [x, y].

• coupt (np.ndarray) – Array of unique time points.

Notes

Missing data are represented as NaN values in the resulting matrix.
