| Abstract: | In this paper, we analyze the statuses, effects and developments of map generalization, and introduce the basic character of "the Survival of the Fittest"theory. We recognize that there are many similar characters between the nature development and the process of the map generalization, and prefer to take"the Survival of the Fittest"theory to map generalization. Also we take care of the traits of "Circle Principle". The applications of using this theory and the principle to generalize map features are expounded in details. Several map generalization methods such as selecting, simplifying and merging have been put forward and the relevant examples are given. |
