Abstract As one of geographic information systems, MapGIS software has been widely applied in geological field in China, which not only has powerful function in map drawing but also provides the secondary development library for users. The forms of expression in geological map and the requirements of legend producing are introduced briefly in this paper. On the basis of components of MapGIS software and according to the map's features of airborne geophysics survey, the authors present the new solutions using C Sharp programming language for rapid maps clipping, legends producing and design and some other work. As a result, the artificial errors are reduced effectively and then the drawing efficiency is raised by multi-times. The key techniques and the codes about components of MapGIS are described in detail.
