Digital map represents an important symbol of Modern Cartography, and with it being the disciplinary core, there appeared several kinds of map products such as map databases, printed maps, electronic maps, mobile maps, and internet maps, etc., as well as variety of map developing and application modes. This paper discusses systematically the theory, method, technology and application of digital map. First of all, theoretic achievements of digital maps were expounded, and then the system structure frame of digital maps was discussed. Secondly, technological development of digital maps on data management, generalization, visualization and thematic map editing were presented. Thirdly, new framework of digital map products was raised up. Finally, some samples of digital map analysis and new way of applications were displayed. All this covered every point in the field of digital map research.
