We lift important results of the theory of samples of discrete ergodic information sources to the multidimensional setting. We use the technique of packings and coverings with multidimensional windows in entropy estimation and universal lossless compression. In particular, we construct sequences of multidimensional array sets which, in the limit, build the generated samples of any ergodic source of entropy rate below an h0 with probability 1 and whose cardinality grows at most at exponential rate h0. Thereby we extrapolate mathematical framework relevant for universal source coding of multi-dimensionally correlated data.
