Based on the fuzzy information optinimization theory, an approach to determine the error detection factors in modeling surveying data of plane similitude conversion was studied, the possibility of using information diffusion estimation was analyzed, and the corresponding error-detecting method and operating procedures were introduced. Through an illus trative calculation and visualization analysis for Xiaodongjiang Dam GPS metamorphase monitoring network, it is demonstrated that the basical theory is reliable and the method is practically feasible. The model may be used as intelligent optimal estimation for error-detecting in the plane similitude conversion.
