In general, Korean people tend to understand the national land as a whole entity for the first time while memorizing the name of the mountain ranges of the Korean peninsula. Meanwhile, the debates on the appropriateness of the Korean mountain range system have been ceaseless since the early 1980s. This study aims to indicate the problems of the current mountain range system and to prepare the correct mountain range map by analyzing the geographical features, the land shape, and the geological structure in a detailed, scientific way in order to close those debates. In order to achieve the best result of this study, a more in-depth analysis of all meaningful aspects and associated documentations was performed. Also, a database on the Korean cyber land shape and major mountains was constituted, and a diverse space analysis by the use of GIS method was attempted.
In addition, according to the literature survey, a mountain range is a "land shape with mountain ridges that are continued in length, and their size and continuance become the criteria of mountain range classification." Thus, in this study, a space database was constituted by collecting a digital elevation model (DEM) of the basic land shape, built digital topographic model, in order to objectively analyze the features of mountain ranges.
After analyzing the status of land shape and performing land shape modeling by the use of this space database, it was concluded that it was hard to accept the theory that the current mountain range system was established on the basis of geographic grounds.
