Because of the projection deformation,we needed to reduce the projection deformation when it reached to a certain value. Usually we took the method of converting the coordinates on the compensation plane,but using the method of compensation ellipsoid transformation to estab-lish compensation coordinate system made us easy understand,so developed the compensation coordinate conversion program using the method of compensation ellipsoid transformation by the platform Visual C+ +,so as to improve the work efficiency and calculation reliability,it got very good practical significance.%由于投影存在着投影变形，当变形达到一定数值时，必须采取措施限制投影变形，通常采用的方法是选取抵偿面对坐标进行抵偿变换，但采用抵偿椭球变换的方法来建立抵偿坐标系的方法意义明确直接，便于理解，因此，为了实现抵偿坐标换算，采用抵偿椭球变换的方法使用Visual C++开发了抵偿坐标换算程序，从而提高了抵偿坐标换算的效率和计算的可靠性，具有很好的实用意义。
