Since the concept was proposed at the beginning of last century, cartography generalization has been gradually changed from full manual operation mode to computer automation mode after decades of improvement and development. However, the level of map automation is still relatively low until now. So, this paper puts forward an integrated representation of geographical model for entity and symbol on the basic of innovative model units and spatial relation model. Then the automatic methods of topological compensation for model entity and cartography compensation for model symbolization are established, we want to explore a solution to solve the worldwide problem of automatic cartography generalization. Finally, this paper look into the future and developmental direction of automatic cartography generalization.
