Abstract: In order to comprehensively reflect the visual and functional characteristics of landmark buildings on the map, a representation design method of composite-symbols for landmark buildings is proposed in this study. Landmark symbols are decomposed into two types of morphemes including building contour characteristics, function and functional status of landmark buildings, morphemes representations are designed respectively. Two operators including jointing and superimposing are used to generate composite landmark symbols based on morphemes. Experiment results show that the meaning of morphemes in the combined landmark symbols are easy to understand, and the combined form can be well accepted for the participants involved in this experiment, which proves the effectiveness of the method proposed in this study.

Key words: landmark, morpheme, symbol design, composite symbol representation
