This paper discusses evaluation criterias on the base of analysizing new means and new tasks of digital map generalization. We presented an automatic evaluation model of large scale digital map generalization. At the same time,we developed an evaluation model that supports AutoMap. AutoMap is a map generalization software developed by Shenzhen Urban Planning and Land Information Center. This model can automatically evaluate the quality of the generalization result. Ultimately,we tested the model and AutoMap with 32 Shenzhen maps in 1∶10000 scale.
