摘　　要：在大比例尺地形图的实际使用过程中,会遇到地形图的坐标系变换,需要把中央子午线为L1的坐标系的地形图转换成中央子午线为L2的坐标系的地形图,称为地形图投影换带变换,而目前许多地形图的形成和使用是在AutoCAD应用软件中进行的。本文提出了适用于AutoCAD中地形图投影换带变换的三种方法:DXF文件法、直接法和相似变换法,并对三种方法进行了比较。In the use of large-scale topographic map, Gauss projection transformation of different projection zones is often encountered. When c map of central meridian L1 needs to be transferred to another one of central meridian L2, this is called as projection transformation of topographic map. But, currently, it is applied mainly in the software of AutoCAD. This paper will give 3 methods for that, which is applicable to AutoCAD software. They are DXF documetn, direct transformation, analogical transformation. Meanwhile, the advantages and disadvantages of them are also compared here.
