Kriging based methods are used for predicting functional data (curves) with spatial dependence. Initially the curves are pre-processed by fitting a Fourier or B-splines basis functions. Then the spatial dependence among curves is estimated by means of the trace-variogram function. Finally the parameters for performing prediction by Ordinary Kriging at unsampled locations are estimated by solving a linear system based on the estimated trace-variogram.
