In this paper reviewed the gradual changes of the locations between spatial entities, and discussed the calculation and assessment of spatial relations similarity in map generalization. We respectively set up conceptual neighborhood for topological relations, directional relations, distance relations of spatial relations mapping, summarized the integrated representation and measurement for spatial relations difference before and after map generalization, and then concluded the formula of spatial relations similarity. Lastly demonstrated rationality and applicability of the integrated representation and measurement for spatial relations difference degree by experimental data's analysis and calculation.
