Accuracy Evaluation and Its Application of SLEUTH Urban Growth Model

Based on multi-temporal TM data,the urban growth of Shenyang city from 1988 to 2004 was simulated by SLEUTH urban growth model.The multiple methods for map comparison and model validation were applied to evaluate the simulation accuracy of the SLEUTH model in Shenyang city.These multiple methods included the relative operating characteristic(ROC) curve,multiple-resolutions error budget,and landscape metrics.The results showed that SLEUTH had a credible precision on the whole,especially for the quantitative simulation of urban growth.However,the simulation accuracy for the spatial location of new development at the pixel scale and for the urban spatial pattern still needed to be improved greatly.Multi-methods research is important for the validation and evaluation of the urban CA models.
