Based on analyzing the disadvantages of traditional approaches, this paper employs a new method, i.e., MNF and MAD transformation, for urban expansion research of Dongying. The accuracy estimation of changing imagery shows that the overall accuracy is 0.901 and the Kappa coefficient is 0.802, suggesting that the method proposed in this paper is efficient.
