We propose a method to construct localized single-particle wave functions using imaginary time projection and thereby determine lattice Hamiltonian parameters. We apply the method to a specific disordered potential generated by an optical lattice experiment and calculate for each instance of disorder the equivalent lattice model parameters. The probability distributions of the Hubbard parameters are then determined. Tests of localization and energy convergence are examined.
