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 application models. This paper discusses the system of digitalmap theory, method and technology, to introduce our research achievement on the one hand, and to sincerely invite cooperation with those cartographers & scientists interested in it, on the other hand. For the theoretic system, the authors expounded the concept, system structure, theoretic bases, and new cartographical ideals brought with digitalmap. For the methodological system, the paper related such items as geoproblems digitalmap suitable to dissolve, and analytical methods with digitalmap, as well as digitalmap datamodel. For the technological system, the paper discussed digitalmap mapping system, mobile digitalmap technologies, etc. Finally, the authors showed some application examples of digitalmap, including the database, electronic version, and Internet version of National Physical Atlas of China, as well as the Electronic Atlas from the Resources & Environment Database in CAS.
