Comparing to Spark, equivalent of all Spark data types are supported. Numpy booleans: np.bool_. Numpy integer data types: np.int8, np.int16, np If there is no trajectory position for the given timestamp, the default behaviour is to interpolate the location: >>> traj . get_position_at ( datetime ( 2018 , 1 , 1 , 12 , 9 )) POINT (6 4.5) To get the trajectory position closest to the given timestamp, specify method=’nearest’: Pandas Series.unique() While working with the DataFrame in Pandas, you need to find the unique elements present in the column.
