| 摘 要： | 为了使由工程平面控制网控制点坐标反算得到的边长与实测边长基本一致,可以采用国家3°带高斯正形投影、抵偿面的3°带高斯正形投影、具有任意带的高斯正形投影以及具有抵偿面的任意带高斯正形投影.通过对这四种高斯正形投影进行对比分析和实例证实,表明具有抵偿面的任意带高斯正形投影,能较好、有效地抑制投影过程中的长度变形.

| Abstract: | In order that the distance obtained through coordinate inverse calculation of control points of engineering plane control network is practically approximate to the distance by field measure, Gauss eonformal projection of 3° zone, Gauss conformal projection of 3° zone with compensation plane, Gauss conformal projection of arbitrary zone and compensating surface with arbitrary zone of Gauss projection can be adopted. Through the comparative analysis and empirical confirmation, it shows that compensating surface with arbitrary zone of Gauss eonformal projection can effectively inhibit the length deformation of the projection. |
