Computer mapping for Atlas of 1∶2 500 000 Geological Maps of Central Asia and Adjacent Areas

Abstract：This paper systematically describes the basic situation of the computer mapping of Atlas of 1∶2 500 000 Geological Maps of Central Asia and Adjacent Areas, which is conducted by the cooperation of experts from China, Russia, Mongolia, Kazakhstan and South Korea. The geographic overview of the mapping region, the drawing of the basic geographical map, the mapping process of the geological map series, the naming rules of each layer, and all parts of the map publication are dealt with in detail. The 1∶2 500 000 basic geographical map is the base of the Atlas of Geological Maps of Central Asia and Adjacent Areas, and its mapping process is similar to that of the Geological Map and Metallogenic Regularity and Mineral Energy Resource Prognosis Map. This paper fully summarizes the principles and methods for computer mapping of Atlas of 1∶2 500 000 Geological Maps of Central Asia and Adjacent Areas from the design and preparation to the publication.
