| 摘 要： | 为把某市的几个区的坐标统一到一个坐标系中，采用3°带高斯投影法、抵偿面的3°带高斯投影法或任意带高斯投影法时，长度变形均超过2．5cm/km。只能采用能较好地控制长度变形的具有抵偿面的任意带高斯投影法，此时整个测区的长度变形小于2．5cm／km。本文针对此情形对上述四种高斯投影变形进行对比分析。

| Abstract: | In order to convert the coordinates of several areas of one city into an uniformed coordinate system, it found that when Gauss conformal projection of 3° zone , Gauss conformal projection of 3° zone with compensation plane or gauss conformal projection of arbitrary zone were adopted, all length deformation exceed 2.5cm/km. Therefore, the only choice is to use the one of arbitrary zone with compensation plane, which can better control the length deformation. As a result, the length deformation of whole field is smaller than 2.5cm/km. For this case, this paper contrasts and analyzes the four deformations of Gauss conformal projection. |
